Question

If POR ~ ASTU, what is the scale factor of APQR to ASTU?

A. 1/5
B. 1/4
C. 5
D. 4

Answer 1

`k = (1)/(5)`

Explanation:

Given

The attached triangles

Required

The scale factor

From the attachment, we have:

`TU = 4`

`QR = 20`

So, the scale factor from PQR to STU is:

`k = (TU)/(QR)`

`k = (4)/(20)`

`k = (1)/(5)`
