Question

Triangle ABC was dilated and translated to form similar triangle A'B'C'.

On a coordinate plane, 2 triangles are shown. Triangle A B C has points (0, 2), (2, 2), and (2, 0). Triangle A prime B prime C prime has points (negative 4, negative 1), (1, negative 1), and (1, negative 6).

What is the scale factor of the dilation?

One-fifth
Two-fifths
Five-halves
5/1

Answer 1

Answer; Five-halves

Explanation:

Put triangles on graph

To find the answer you divide the A' to B' by the A to B distance.

So you divide 5/2
