Define translation in geometry.

Back

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

What is a rotation in geometry?

Back

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

What is a reflection in geometry?

Back

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

Define dilation in geometry.

Back

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

What is the rule for rotating a point 90 degrees counterclockwise around the origin?

Back

The rule is (x,y) → (-y,x).

What is the rule for rotating a point 360 degrees around the origin?

Back

The rule is (x,y) → (x,y), meaning the point remains unchanged.

How do you identify a translation on a graph?

Back

A translation can be identified by a consistent shift of the shape in a specific direction without changing its orientation.
