Question

Rectangle QRST is dilated with the origin as the center of dilation to create rectangle Q'R'S'T'.

Which rule represents the dial toon applied to rectangle QRST to create triangle QRST

Answer 1

Rule: dilation about the origin by a scale factor of 2

Step-by-step explanation:

Given

See attachment for QRST and Q'R'S'T

Required

The dilation rule

First, we calculate the scale factor (k)

From the attachment, we have:

`QR = 4`

`Q'R' = 8`

k, is then calculated as:

`k = (Q'R')/(QR)`

`k = (8)/(4)`

`k =2`

Hence, QRST is dilated by a factor of 2
