What does it mean to translate a figure?

Back

To translate a figure means to slide it in a straight line from one position to another without changing its shape or orientation.

What is dilation in geometry?

Back

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

How does a rotation transformation work?

Back

A rotation transformation turns a figure around a fixed point, called the center of rotation, by a specified angle.

What is the effect of a reflection across the y-axis on the coordinates (x, y)?

Back

The reflection across the y-axis changes the coordinates to (-x, y).
