Question

Line segment AB is dilated to create line segment A'B' using point Q as the center of dilation. What is the scale factor?

Answer 1

The distance from point Q to point A is 1.25

The distance from point A to point A' is 1.25

The distance from point Q to point A' is 2.50. This is twice the distance from point Q to point A.

The scale factor is 2.

1.25 + 1.25 = 2.50

2.50 / 1.25 = 2
