Topic: triangle congruence postulates (SSS, SAS, ASA)

Activity 2 Shown below are pairs of triangles in two sets. Use them to answer the questions that follow. A B G S Hotto M B EQuestions: 1. Describe the pairs of triangles in set A. 2. Describe the pairs of triangles in set B. 3. Differentiate the pairs of triangles in set A from set B.Activity 4 Read each item carefully. Choose the letter of the correct answer. 1. Vincent knows that AB = XY and AC = XZ. What other information must he know to make AABC = AXYZ by SAS postulate? A. LB = LY C. LC = LZ B. LA = LX D. LC = LX 2. Grace knows that in AMIG and AJAN, MI = JA, IG = AN, and MG = JN. Which postulate can she use to make the triangles congruent?' A. ASA C. SSS B. SAS D. AAS 3. Name the corresponding congruent parts as marked that will make each pair of triangles congruent by SAS. A. BY = NR, LBOY = LNOR, BO = NO B. BO = NO, LBOY = LNOR, RO = YO C. YO = OR, BO = ON, LBOY = LNOR D. LB = LN, BO = NO, OY = OR 4. Use the marked triangles to write a correct congruence statement. A. LT = MS C. LT = MS S LO = ME OL = ME Of = ES OT ~ SE ALOT = AMES ALOT = AMSE B. LT = SM D. TL = MS LO = ME LO = ME Of = ES OT = ME E M ALOT = ASME ATOL = ASME 5. If the congruent corresponding parts are marked, what congruence postulate will make ABEC = ABAC? A. ASA C. SSS B. SAS D. AAS 6. Given information is shown marked on the diagram at the right, what additional corresponding parts needed to make A BEC = ABAC by SAS Congruence Postulate? A. LE = LA C. LB = LC B. LEBC = LABC D. LBCE = ZBCA EActivity 5 Corresponding congruent parts are marked. With the specified congruence postulate, identify the additional corresponding parts needed to make the triangles congruent and color the block/cell that corresponds to the correct answer. 1. a. SAS AB = DE AB = ED BA = DE b. ASA LA= CD LC= CF CA = CE A 2. a. SAS CLOT = LPOM ZLOT = CMOP CTOL = ZMOP b. SSS LT = PM TL E MP LT = MP a. SAS CD = BA DC = BA CD = AC b. ASA CDAC = ZBAC LDAC = CBCA LDAC = _CAB 4 a. SSS ON = NE DN = BN DN = EN b. SAS
