Geometry Concepts

Front

Center of symmetry

Back

A point in which a figure can be rotated onto itself.

Front

Composition of transformations

Back

When a transformation is applied to a figure and then another transformation is applied to its image.

Front

Glide reflection

Back

The composition of a translation followed by a reflection in a line parallel to the translation vector.

Front

Line of symmetry

Back

An imaginary line that separates a figure into two congruent parts.

Front

Line symmetry

Back

Each half of a figure matches the other half exactly.

Front

Magnitude

Back

The length of a vector from the initial point to the terminal point.

Front

Magnitude of symmetry

Back

The smallest angle through which a figure can be rotated so that it maps onto itself.

Front

Order of symmetry

Back

The number of times a figure maps onto itself.

Front

Point of symmetry

Back

The point about which a figure is rotated.

Front

Point symmetry

Back

A figure or graph has this when a figure is rotated one hundred eighty degrees about a point and maps exactly onto the other part.
