If a shape in Quadrant 2 reflects over the x-axis, which quadrant will the reflection be in?

Back

Back

The sides and angles do not change when you reflect.

Front

Front

What is a translation in geometry?

Back

A transformation that slides a figure in a straight line from one position to another without changing its shape or size.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point called the center of rotation.

Front

What is a reflection in geometry?

Back

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

Front

What does it mean for two shapes to be congruent?

Back

They have the same shape and size, but may be in different positions.

Front

What is the center of rotation?

Back

The fixed point around which a figure rotates.
