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

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
