Is the following a proof? If not, why not? Theorem: The base angles of an isosceles triangle are equal. Proof: Let ABC be an isosceles triangle with sides AB = AC. Then ABC is congruent to ACB because the corresponding sides are equal: AB = AC, BC = CB, AC = AB. Here, corresponding angles are equal: in particular ̸ ABC = ̸ ACB. (You may assume the usual geometrical properties of congruent triangles.)

If AABC is an isosceles triangle, which statement explains whether there is enough information to prove that ZADB and ZCDB are right angles? AD C A No, it is not known if ZA 2 ZC, so AABD and ACBD cannot be proven congruent. No, it is not known if BD is the angle bisector of ZABC or if D is the midpoint of AC. Thus, AABD and ACBD В cannot be proven congruent. Yes, AABD ACBD by the SAS Congruence Postulate and ZADB and ZCDB are congruent because of CPCTC. C Since ZADB and ZCDB are also a linear pair, they sum to 180° and each must equal 90°, making them both right angles. Yes, AABD ACBD by SSS and ZADB and ZCDB are congruent because of CPCTC. Since ZADB and ZCDB are also a linear pair, they sum to 180° and each must equal 90°, making them both right angles. B
