Back

The main types of transformations are translation, rotation, reflection, and dilation.

Front

What does it mean to translate a shape?

Back

To translate a shape means to slide it in a straight line without changing its size or orientation.

Front

What is a rotation in geometry?

Back

A rotation is turning a shape around a fixed point at a certain angle.

Front

What does it mean for two sides to correspond in similar triangles?

Back

Corresponding sides in similar triangles are the sides that are in the same relative position in each triangle.

Front
