Agenda 1 Review U3H2 2 Review of Parallelograms and Trapezoids 3 Rectangles, Rhombuses, and Squares 4 Cool-Down
DeDinitions of Quadrilaterals Ø Everyone will receive a Green Paper. Title the top: DeMinitions of Quadrilaterals Ø Draw a line in the middle of the paper creating two rectangles. Ø Draw one line splitting one rectangle and into two halves. Draw two lines splitting the second rectangle into 3 halves.
DeDinitions of Quadrilaterals Ø Title one box trapezoid. What is the deminition of a trapezoid? Ø Draw a diagram! Ø In the same box, title it isosceles trapezoid. What is the deminition of an isosceles trapezoid? Ø Title a new box Parallelogram. What is the deminition of a parallelogram? Ø We will Mill in the remaining boxes later!

U3A15 Rectangles, Rhombuses, and Squares I will leave one page blank for my next set of SB notes. Today s Lesson #: U3A15 Topic: Rectangles, Rhombuses, and Squares LO#3: Develop and prove properties of rectangles, rhombuses, and squares.
U3A15 Rectangles, Rhombuses, and Squares DeIinition of a Rectangle o A quadrilateral with four right angles.
U3A15 Rectangles, Rhombuses, and Squares Properties of Rectangles o If a quadrilateral is a rectangle, then Ø It is a parallelogram. Ø It s diagonals are congruent. (AC BD)

Whiteboards!
U3A15 Rectangles, Rhombuses, and Squares DeIinition of a Rhombus o A quadrilateral with four congruent sides.
U3A15 Rectangles, Rhombuses, and Squares Properties of Rhombuses o If a quadrilateral is a rhombus, then Ø It is a parallelogram. Ø It s diagonals are perpendicular. (AC BD) Ø Each diagonal bisects a pair of opposite angles.
U3A15 Rectangles, Rhombuses, and Squares Pg. 219 Complete #13 in your groups. Provide justimications in the My Notes column. (5 minutes)
U3A15 Rectangles, Rhombuses, and Squares DeIinition of a Square o A quadrilateral with four right angles and four congruent sides.
