What happens to a shape during a translation?

Back

A translation moves a shape from one location to another without changing its size, shape, or orientation.

What is a reflection?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

How do you determine the direction of a translation?

Back

The direction of a translation is determined by the values added or subtracted from the coordinates of the shape.

What does it mean for figures to be congruent?

Back

Congruent figures have the same shape and size, meaning they can be superimposed on each other.

Front

What does it mean for figures to be similar?

Back

Similar figures have the same shape but may differ in size; their corresponding angles are equal and sides are proportional.
