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?

Back

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

What does it mean for a transformation to be rigid?

Back

A rigid transformation is one that preserves the shape and size of a figure, meaning the original and transformed figures are congruent.

What is the scale factor in dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the original figure.
