Question

What is the scale factor of Triangle PQT to Triangle PRS?

Answer 1

1:2

Explanation:

Given ΔPQT ~ ΔPRS

The ratios of the sides of these triangles is the same

We are given QT = 15 and PS = 30

QT/PS= 15/30 = 1/2 or in proportion notation:

Therefore the scale factor 1/2 which can be written as 1:2
