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.

Explain reflection in geometry.

Back

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

What is dilation in geometry?

Back

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

How do you describe a translation of 4 units right and 2 units up?

Back

This means moving every point of the shape 4 units to the right and 2 units up.

What is the effect of reflecting a shape over the x-axis?

Back

Reflecting a shape over the x-axis flips it vertically, changing the sign of the y-coordinates.
