Define translation in geometry.

Back

Translation is a transformation that slides a figure in a straight line from one position to another without changing its shape or orientation.

What is reflection in geometry?

Back

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

Define rotation in geometry.

Back

Rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

How do you identify a translation on a coordinate grid?

Back

A translation can be identified by observing that all points of the figure move the same distance in the same direction.

What does it mean to reflect a shape across the x-axis?

Back

Reflecting a shape across the x-axis means that each point of the shape is flipped over the x-axis, changing the sign of the y-coordinate.

What is the result of rotating a shape 90 degrees clockwise?

Back

Rotating a shape 90 degrees clockwise moves each point of the shape to a new position that is 90 degrees to the right around the center of rotation.
