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

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
