Question

Draw a dilation of the figure using the given factor

Answer 1

Explanations;

The coordinate point of the given triangles are:

A = (1, 1)

B = (2, -1)

C = (-2, 0)

If the coordinates are dilated by a scale factor k = 2, the resulting coordinates of the pre-image will be:

A' = 2(1, 1) = (2, 2)

B' = 2(2, -1) = (4, -2)

C' = 2(-2, 0) = (-4, 0)

The resulting dilated figure is as shown:
