Question

Angle ABC is taken by a dilation with centerpoint, P and scale factor of four to angle A’B’C’ the measure of angle, BCA is 75° what is the measure of angle B’C’A’

Answer 1

75°

Explanation:

You want to know the measure of the image angle B'C'A' after angle A'B'C' is dilated by a factor of 4 about point P. Angle BCA is 75°.

Dilation

Dilation does not affect angle measures, so angle B'C'A' has the same measure as angle BCA, 75°.

m∠B'C'A' = 75°
