Question

Triangle ABC is dilated by a scale factor of 3, which statement is true of the image of Triangle A’B’C’?   AB = 3A'B' 3BC = B'C' m∠A'=3(m∠A) 3(m∠C')=m∠C

Answer 1

3BC = B'C'

Explanation:

Triangle ABC is dilated by a scale factor of 3 to get A’B’C', which means Triangle A’B’C' length will be 3 times as Triangle ABC, but the angles won't be affected.

so 3BC = B'C' will be the correct answer.
