Which is a valid conclusion that can be d

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

The triangles below are right triangles. Whiich Theorem could be used to prove the Triangles are similiar?

2. Which statement about the picture below is true? 4 The angles are supplementary. Both angles appear to be acute angles. Both argles are adjacent. The angles are complementary. 3,
