Question

A(-2,1), B(1,0), and CC –3, 2). Draw the image after a dilation with a scale factor of 2

Answer 1

Please check the attached figure.

• The red-colored triangle represents the image triangle after a dilation with a scale factor of 2.

Explanation:

Given the vertices

• A(-2, 1)

• B(1, 0)

• C(-3, 2)

A rule of dilation by a scale factor of 2

(x, y) → (2x, 2y)

As the scale factor > 1, thus the image will be enlarged.

The vertices of the image after dilation by a scale factor of 2 are:

(x, y) → (2x, 2y)

A(-2, 1) → A'(-4, 2)

B(1, 0) → B' (2, 0)

C(-3, 2) → C' (-6, 4)
