1 Name (print first and last) Per Date: 12/17 due 12/ ongruence: S and Geometry Regents Ms. Lomac SLO: I can S and to prove the isosceles triangle theem. (1) Does guarantee that triangles congruent? To answer this, complete the questions below. E (a) List the pairs of congruent angles f the diagram at left: D F E,, Does DEF map to by rigid transfmation? beca _ D F (b) List the pairs of congruent angles f the diagram at E right:,, Does DEF map to by rigid transfmation? beca D F E _ D F (c) ased on your responses in parts (a) and (b), does guarantee congruent triangles (that means always)? beca
2 (2) Does SS guarantee congruent triangles? ' ' ' ' ' ' (a) List the pairs of congruent parts f the diagram at left:,, This is called SS beca the angles are/are not (circle one) between the sides. Does ''' map to by rigid transfmation? beca _ So, the triangles are/are not (circle one) congruent. ' ' (b) List the pairs of congruent parts f the diagram at right:,, re the pairs of sides and angles the same as the ones in part (a)? Is this SS? Does ''' map to by rigid transfmation? beca So, the triangles are/are not (circle one) congruent. ' 1 ' 3 ' 5 ' ' ' ' ' ' 2 ' ' 4 ' ' ' ' (c) ased on your responses in parts (a) and (b), does SS guarantee congruent triangles (that means always)? beca (d) In diagrams 1 5 at right, SS is still given. F each diagram, write if the pair of overlapping triangles are ' congruent not, if they are not In diagram 5, finally coincides with and the angle measures. So, and ''' are triangles. So, SS guarantees congruent triangles, but ONLY ' when the two triangles are triangles. Since it only happens with triangles, we don t call it SS. Instead, we call it Hypoten Leg ongruence (). ' '
3 (3) We have looked at SS, S, SSS,, SS, and the special case of SS which is HL. IRLE the shtcuts that guarantee congruent triangles. re there any other shtcuts? What about S? (a) Use the diagram at right to describe the similarities between S and S. (b) Use the diagram at right to describe the differences between S and S. (c) Lets give angles and angle measures to see what we can say about the triangles. Let = 30 and = 70. ased on this infmation, write the measure ' of each of the angles below: ' = ' = ' = ' = ' What do you notice about and? (d) Prove what you observed in part (c). (1) n equation f is + + = (2) n equation f ''' is + + = (3) We know that + + = + + beca we can substitute. (4) We also know that + = + beca the angle pairs are congruent. (5) We can write + + = + + by substituting equal values from step 4 into the equation from step 2. (6) Now we know that =. (e) SO WHT? Well, we can always fce an S situation into an S situation like we did above, but that is a lot of extra wk. Since we learned in (d) that we can always fce S into S, we can just as a shtcut f proving triangles congruent and not bother with the extra wk of fcing into S. (3) omplete the triangle congruence notes on the Unit 5 notes packet.
4 (4) Given D, D, 1 2 (HINTS: 6 steps, you ll need linear pair OR exteri angle theem) Prove: D D hoose SS S S (5) Given D D, D, D (HINTS: 4+ steps) Prove: D D hoose SS S S
5 (6) Given, DE EF, EF, F D (HINTS: segments + same segment are =) Prove: DEF hoose SS S S (7) Given PR R, P R, R is equidistant from P and P (HINTS: 7+ steps, equidistant means... ) Prove: PR bisects P hoose SS S S
6 (8) Given P, R, W is the midpoint of P (HINTS: 4+ steps, what does midpoint give us, highlighters redraw) Prove: RW W hoose SS S S (9) Given R U, rectangle RSTU (HINTS: 6+ stepsprove RS UT, what do we know about rectangle sides and angles, can we get base angles to prove sides) Prove: RU is isosceles hoose SS S S
