Glide Reflection

A composition of transformations that indicates a translation followed by a reflection

Corresponding Angles

A pair of angles that have the same relative position in congruence or similar figures

Corresponding Sides

A pair of sides that have the same related position in congruent figures

Composition of Transformations

A preimage can map an image through a combination of transformation

Reflection

A transformation over a line is a transformation in which each point of the original figure has an image that is the same distance from the of the other

Translation

A transformation that moves every point of a figure the same distance in the same direction

Isometry

A transformation that preserves length, angle measures, parrell lines, a distance between points or a figure

Rotation

A transformation that turns a figure about a fixed point called the center of rotation figures can be turned clockwise or clockwise

Rotation

A transformation that turns a figure about a fixed point called the center of rotation. Figures can be turned clockwise or counterclockwise

Transformation

An operation that maps moves or changes a geometric figure in a new figure

Rigid Motion

The action of moving a geometric figure without alltering its shape or size

Line of Symmetry

The line where you could fold the image and have two halves both halves match exactly

Angle of Roation

The measure of the angle by which a figure is rotated such that the preimage is the image

Congruent

figures that have corresponding sides and angles

Rotational Symmetry

if there is a center point around which the object is turned "theta" and the object looks the same It has
