Question

Hello :) Please help me solve this Explain answer

Answer 1

Answer:

$Scale\ Factor = \frac{1}{2}$

ABC dilated

Step-by-step 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:

$Scale\ Factor = \frac{DE}{AB}$

$Scale\ Factor = \frac{1}{2}$

i.e. ABC was dilated by 1/2
