Transformation of Points

A double reflection over the x- and y-axes is the same as a ____________ of ______.

• Rotation of 180 Degrees

• Rotation of 90 Degrees

• Reflection over the x-axis

• Reflection over the y-axis

A translation

• is a transformation that preserves distance and angle measures.

• is a transformation that moves or slides points the same distance and in the same direction.

• is a transformation that flips points across a line of reflection.

• is a transformation that turns points about point called a center of rotation.
