Help me please on this question. Thanks.

In the diagram below what is the approximate length of the minor arc ab

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

Whose conclusion is correct? choose all that apply. (two max) elijah emily edward esme
