Question

Examine the figures below. What is the scale factor of dilation that maps ∆ABC onto ∆A'B'C'?A. 2B. 12C. −12D. −2

Answer 1

Given:

We get the points C'(-4,-4) and C(-2,-2) from the graph.

A'(-2,4) and A(-1,2).

Required:

We need to find the scale factor of dilation that maps ∆ABC onto ∆A'B'C'.

Step-by-step explanation:

Consider the map C(-2,-2) onto C'(-4,-4).

The ratio of the x-coordinates is

`(-4)/(-2)=(4)/(2)=2`

The scale factor is 2.

Final answer:

The scale factor is 2.
