Performing transformations

If the triangle ABC is dilated using a scale factor of k=2, what will be the coordinates of A' after the transformation?(Click the picture to zoom in on it)

• A'(1.5, -1.5)

• A' (-6, 6)

• 72 ft by 18ft

• 9 ft by 4 ft

• 28 ft by 7 ft

• 327 ft by 88 ft

Which property is ONLY for dilations?

• Corresponding angles congruent

• Corresponding side length ratios are congruent

• Same shape, different sizes

• Same position

Dilate Point B by a scale factor of 3:

• (12,0)
