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.

What does it mean to map a shape?

Back

To map a shape means to apply a transformation to it, resulting in a new position or orientation of the shape.

How do you perform a reflection over the y-axis?

Back

To reflect a point (x, y) over the y-axis, the new coordinates become (-x, y).

What happens to the coordinates of a point after a 180-degree rotation about the origin?

Back

After a 180-degree rotation about the origin, the coordinates of a point (x, y) become (-x, -y).
