Front

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?

Back

A 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.

How do you identify a rotation in a transformation?

Back

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

What is the difference between reflection and rotation?

Back

Reflection flips a shape over a line, while rotation turns a shape around a point.

What does it mean to rotate a shape 90 degrees clockwise?

Back

Rotating a shape 90 degrees clockwise means turning the shape 90 degrees to the right around the center of rotation.

What is the effect of a translation on a shape's orientation?

Back

A translation does not change the shape's orientation; it only changes its position.
