What does translation mean in geometry?

Back

Translation means moving a shape from one position to another without changing its size, shape, or orientation.

How do you describe a translation?

Back

A translation can be described by how far and in which direction a shape moves, often using coordinates.

What is a rotation in geometry?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation.

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the direction of a clock's hands, while counterclockwise rotation moves in the opposite direction.

What is a reflection in geometry?

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 scale factor in a dilation?

Back

The scale factor is determined by the ratio of the lengths of corresponding sides of the original shape and the dilated shape.

What is the effect of a scale factor greater than 1 in dilation?

Back

A scale factor greater than 1 enlarges the shape.
