Define translation in geometry.

Back

Translation is a transformation that slides a shape from one position to another without turning it.

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point called the center of rotation.

Explain reflection in geometry.

Back

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 does a translation affect the coordinates of a shape?

Back

In a translation, the coordinates of each point of the shape are changed by adding a constant value to the x and y coordinates.

What happens to a shape during a rotation?

Back

During a rotation, each point of the shape moves in a circular path around the center of rotation.

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create its mirror image.

How do you identify a rotation transformation?

Back

A rotation transformation can be identified by the angle of rotation and the center of rotation.
