CCSS.8.G.A.2

A type of transformation where a figure is “flipped” over a line of symmetry and a mirror image is produced.

• rotation

• translation

• dilation

• reflection

Which of the following are congruence transformations? Select ALL that apply.

• Rotations

• Translations

• Reflections

• Dilations with scale factor other than 1

Is triangle ABC congruent to triangle A'B'C'?

• They are congruent because triangle ABC maps to triangle A'B'C' by a translation which preserves angle measure and side length.

• They are similar because triangle ABC maps to triangle A'B'C' by a dilation and a reflection which preserves angle measure and side lengths are proportional.

• They are congruent because triangle ABC maps to triangle A'B'C' by a reflection which preserves angle measure and side length.

• They are similar because triangle ABC maps to triangle A'B'C' by a dilation which preserves angle measure and side lengths are proportional.

The __________ is the ratio of a length of the image to the corresponding length on the original figure.

• reduction
• enlargement
• scale factor
• center of dilation
