1 Chapters 7 & 8 Parallel and Perpendicular Lines/Triangles and Transformations
2 7-2B Lines I can identify relationships of angles formed by two parallel lines cut by a transversal. 8.G.5
3 Symbolic Representations AB CD Translation: line AB is parallel to line CD n m Two arrow heads are the symbol here L Translation line n is parallel to line m
4 Symbolic Representations AB CD Translation: line AB is perpendicular to line CD m The square is the symbol here Translation: line n is perpendicular to line m n
5 In geometry, a line, line segment, or ray that intersects two or more lines at different points is called a transversal A l m B AB is an example of a transversal. It intersects lines l and m. Note all of the different angles formed at the points of intersection. 3/26/2017 LSowatsky 5
6 Two lines divide the plane into three regions. The region between the lines is referred to as the interior. The two regions not between the lines is referred to as the exterior. Exterior Interior Exterior 3/26/2017 LSowatsky 6
7 When a transversal intersects two lines, eight angles are formed. These angles are given special names. Interior angles lie between the two lines. Alternate Interior angles are on the opposite sides of the transversal t l m Exterior angles lie outside the two lines. Consecutive Interior angles are on the same side of the Alternate Exterior transversal. angles are on the opposite sides of the 3/26/2017 LSowatsky transversal. 7
8 When a transversal crosses two lines, the intersection creates a number of angles that are related to each other. Note 1 and 5 below. Although one is an exterior angle and the other is an interior angle, both lie on the same side of the transversal. Angle 1 and 5 are called corresponding. angles Give three other pairs of corresponding angles that are formed: 4 and 8 3 and 7 2 and /26/2017 LSowatsky t l m
9 Parallel lines, transversals, and angles measures: Congruent: Alternate Interior Angles Alternate Exterior Angles Corresponding Angles Supplementary: Consecutive (same side) Interior
10 Example:
11 Solve a real-world problem When sunlight enters a drop of rain, different colors of light leave the drop at different angles. This process is what makes a rainbow. For violet light, m 2 = 40. What is m 1? How do you know?
12 Homework: p. 412 #13-27, 29-33
13 8-1B Similar Polygons I can identify similar polygons and find missing measures of similar polygons 8.G.4
14 Two figures that have the same shape but not necessarily the same size are similar. Two polygons are similar if: 1. corresponding angles are congruent. 2. corresponding sides are proportional. notation: ~ means similar
15 Similar polygons C B F G A D E H AB BC = = FG = CD DA EF GH HE
16 Scale Factor: The ratio of two corresponding sides, if two sides are similar
17 X 6 Y Q 4 R P 8 S W 12 Z WX PQ = = 3 2 XY QR = 6 4 = 3 2 YZ = 9 RS 6 = 3 2 ZW = 12 SP 8 What is the scale factor? = 3 2 Since the two figures are similar, you can write WXYZ ~ PQRS.
18 Example: Using Similar Polygons Quadrilateral JKLM is similar to PQRS. Find the value of z. J M 10 K 15 L R 6 Q Z P S Set up a proportion that contains PQ KL QR 15 6 = = JK PQ 10 Z Write the proportion using corresponding parts Substitute Z = 4 Cross multiply and divide by 15.
19 Perimeter of Similar Figures: If two figures are similar, the ratio of the perimeters is the same as the scale factor scale factor a b Perimeter Perimeter A B
20 Example: A model of a billboard has a side length of 3 inches. The corresponding side on the actual billboard is 4 ft long. The model has a perimeter of 42 inches. What is the perimeter of the actual billboard?
21 Homework: p. 467 #5-14, 16, 17, 19, 20
22 8-2B Pythagorean Theorem I can Use the Pythagorean theorem to find missing side lengths in right triangles and use the converse to determine if a triangle is a right triangle.
23 If two measures of the sides of a right triangle are known, The Pythagorean Theorem can be used to find the measure of the third. side a c b
24 Find the length of the hypotenuse if a = 12 and b = 16.
25 Example: Write an equation you could use to find the length of the missing side of the right triangle. Then find the missing length. Round to the nearest tenth, if necessary. a cm 33 cm 28 cm
26 Converse of Pythagorean Theorem: If a b c is a true for your triangle, then it is a right triangle. *Use to check to see if a triangle is right or not
27 Example: Determine whether each triangle with sides of given lengths is a right triangle. Justify your answer. 1) 36, 48, 60 2) 4, 7, 5
28 Homework: p. 485 #6-26, 28
29 8-2D Distance on the Coordinate Plane I can find the distance between two points on the coordinate plane 8.G.8
30 Find the Distance Between: 1. Points A and B 2. Points B and C 3. Points A and C
31 The Distance Formula The distance d between two points A (x 1, y 1 ) and B (x 2, y 2 ) is d 2 2 x x y y /20/2011 LSowatsky 31
32 Example: Graph the ordered pairs (1, 3) and (-2, 4). Then find the distance between the points. Round to the nearest tenth. Use calculator at end.
33 Example: Find the distance between R (-2, 6) and S (6, -2) to the nearest tenth. Note: be careful using your calculator use at the very end. 6/20/2011 LSowatsky 33
34 Homework: p. 496 #9-14, 17-22, 26, 27
35 8-3A Translations I can graph translations on the coordinate plane. 8.G.1, 8.G1a, 8.G1b, 8.G.1c, 8.G.3
36 Vocabulary: Transformations a movement of a geometry shape Preimage the image before the transformation (original figure) Image the figure after the transformation New points are called primes LSowatsky 36
37 Translations: A slide of the preimage where each point moves the same distance in the same direction 2 ways to find new points (primes) 1) use a graph 2) calculate new coordinates LSowatsky 37
38 Example: Draw the image of the figure after the indicated translation.
39 1)Graph ordered pairs 2)Translate figure to create image 3)List new ordered pairs
40 Homework: Workbook p.145 & 146
41 8-3B Reflections I can graph reflections on the coordinate plane. 8.G.1, 8.G1a, 8.G1b, 8.G.1c, 8.G.3
42 Reflection - A flip over a line of reflection to create a mirror image (each point is moved to other side of line To find prime points of the image: If it reflects over the x-axis, x value stays same and y-value is opposite sign If it reflects over the y-axis, x value is the opposite sign and y value stays the same LSowatsky 42

45 Homework: worksheet
46 8-3D Rotations I can graph rotations on the coordinate plane. 8.G.1, 8.G1a, 8.G1b, 8.G.1c, 8.G.3
47 Rotations: turn the geometric figure Dependent on: Direction (clockwise vs. counterclockwise) Degree (90, 180, 270, 360 multiples of 90) LSowatsky 47
48 Example: 90 rotation Look for pattern and compare ordered pairs of vertices Preimage: A (-5, 7) A (7, 5) B (-1, 6) B (6, 1) C (-3, 2) C (2, 3) General Rule: For each clockwise 90 rotation, switch the x and y and change sign of new y LSowatsky 48
49 1)Write the ordered pairs 2)Rotate using rule 3)Graph image using new ordered pairs
50 1)Write the ordered pairs 180 degrees ccw about the origin 2)Rotate using rule 3)Graph image using new ordered pairs
51 Homework: worksheet
52 8-3E Dilations I can Use the scale factor to graph dilations on the coordinate plane. 8.G.3
53 Dilations: (Stretching/Shrinking) Dilations use a scale factor to reduce or enlarge shapes. Every dilation has a center and a scale factor. Most of the time it is the origin (0, 0) Scale Factor: tells you how many times larger or smaller your image will be. The new shape and the image are similar. Dilations are also called similarity transformations.
54 How do we locate dilation images? A dilation is a transformation who preimage and image are similar. A dilation is not an isometry. Every dilation has a center and a scale factor k, k >0. The scale factor describes the size change from the original figure to the image.
55 Example 1: Quadrilateral ABCD has vertices A(-2, -1), B(-2, 1), C(2, 1) and D(1, -1). Find the coordinates of the image for the dilation with a scale factor of 2 and center of dilation at the origin. B C B C A D A D
56 Example 2: F(-3, -3), O(3, 3), R(0, -3) Scale factor 1/3 O O F R F R
57 The dilation is an enlargement if the scale factor is > 1. The dilation is a reduction if the scale factor is between 0 and 1.
