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 rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

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 keeps its proportions the same.

How do you identify a reflection transformation?

Back

A reflection transformation can be identified by a mirror line where the original shape and the reflected shape are equidistant from the line.

How can you determine if a transformation is a rotation?

Back

A transformation is a rotation if the shape is turned around a fixed point by a certain angle.
