Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a figure the same distance in the same direction.

What is a rotation?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a specified angle.

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

Define dilation in geometry.

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

What is the scale factor in dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during dilation.

Front

True or False: Dilation preserves the shape of a figure.

Back

True, dilation preserves the shape but not the size.

What is an isometry?

Back

An isometry is a transformation that preserves distances and angles, resulting in congruent figures.

Which transformation is NOT an isometry?

Back

Dilation is NOT an isometry because it changes the size of the figure.
