Question

Right angle ABC is taken by a dilation with center P

and scale factor to angle A'B'C'.
12
What is the measure of angle A'B'C'?

Answer 1

`\angle A'B'C' = 40`

Explanation:

Given

`\triangle ABC` and
`\triangle A'B'C'`

Required

The measure of
`\angle A'B'C` after the dilation

Dilation does not change the measure of angle of a shape.

So, we have:

Before dilation

`\angle ABC = 40`

This implies that: after dilation

`\angle A'B'C' = 40`
