What are the three main types of transformations?

Back

The three main types of transformations are translation (slide), rotation (turn), and reflection (flip).

Front

Define translation in geometry.

Back

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

Define rotation in geometry.

Back

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

Define reflection in geometry.

Back

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

What is the effect of a 90-degree rotation on a shape?

Back

A 90-degree rotation turns the shape a quarter turn in a clockwise or counterclockwise direction.

What happens to a shape during a reflection over the x-axis?

Back

During a reflection over the x-axis, the y-coordinates of the points of the shape are inverted.

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips a shape over a line.

How can you identify a translation?

Back

A translation can be identified by the consistent movement of all points in the same direction and distance.

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.
