What does it mean to rotate a shape?

Back

To rotate a shape means to turn it around a fixed point, called the center of rotation, by a certain angle.

What is reflection in geometry?

Back

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

How do you describe a translation of a shape?

Back

A translation can be described by how far to move the shape horizontally and vertically, often expressed as (x, y) changes.

What is the result of reflecting a point across the x-axis?

Back

The y-coordinate of the point changes sign, while the x-coordinate remains the same.

What is a dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape, using a scale factor.
