Question

Hello :)
Please help me solve this

Explain answer

Answer 1

`Scale\ Factor = (1)/(2)`

ABC dilated

Explanation:

Given

Triangles ABC and DEF

Required

Determine the scale of dilation

First, we pick a side on ABC

`AB = 6`

Pick a corresponding side on DEF

`DE = 3`

The scale factor is then calculated as:

`Scale\ Factor = (DE)/(AB)`

`Scale\ Factor = (1)/(2)`

i.e. ABC was dilated by 1/2
