Question

Given:
CM bisects AB
AC = BC
Based on the given information and the algebraic and geometric properties presented or proven thus far, choose the congruence theorem that could be used to prove the triangles congruent. If it is not possible to prove the triangles are congruent, choose "not possible".

not possible

Answer 1

please help

Answer 2

Make sure to include the diagram beforehand

But it told us that AC and BC are equal, so they have the red mark

CM is congruent to itself (another red mark)

Because CM is bisecting AB, AM and BM are congruent

-- We proved 3 sides
