In the straightedge and compass construction of the equilateral triangle below, which of the following reasons can you use to prove that
2 CAB = ZACB?
B
A. AB and AC are radii of the same circle, and AB and BC aradii
of the same circle, So AB = AC and AB = BC. AC and BC are
both congruent to AB, SO AC = BC. Thus, triangle ABC is an
equilateral triangle Faulat
