9 A student wants to prove that the base angles of an isosceles triangle are congruent. The student draws isosceles triangle ABC with base angles B and C, as shown below. B M Point M is drawn as the midpoint of BC. Which of the following could be used as part of the proof that ZB & ¿C? Select ALL that apply. A. AM AM because of the Symmetric Property. B. BM = CM because of the definition of a midpoint. C. AB = AC because of the definition of an isosceles triangle. D. A ABM = AACMbecause of the SAS triangle congruence criterion. E. ZB = 2C because corresponding parts of congruent triangles are congruent.
