Question

Angle ABC is taken by a dilation witch enter P and Scale factor 1/3 to angle A'B'C'. The measure of angle ABC is 21∘. What is the measure of angle A'B'C'.

Answer 1

Answer:

Step-by-step explanation:

Given

ABC dilated to A'B'C'

$Scale\ Factor = \frac{1}{3}$

Required

Determine <A'B'C'

From geometry, we understand that dilation do not affect angles.

In other words, when ABC is dilated to A'B'C, the angles of A'B'C' retains the angles in ABC.

Using the above analysis:

Hence,
