Geometry Concepts

Front

Rigid Motion

Back

A transformation that preserves length and angle measure.

Front

Congruent Figures

Back

Geometric figures that have the same size and shape.

Front

CPCTC

Back

Congruent Parts of Congruent Triangles are Congruent.

Front

ASA (angle-side-angle)

Back

If two angles and the included side of one triangle are congruent to two angles and the included side of another, then the triangles are congruent.

Front

SSS (side-side-side)

Back

If all 3 sides of one triangle are congruent to all 3 sides of another, then the triangles are congruent.

Front

SAS (side-angle-side)

Back

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another, then the triangles are congruent.

Front

AAS (angle-angle-side)

Back

If two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another, then the triangles are congruent.

Front

HL (hypotenuse leg)

Back

If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another, then the triangles are congruent.

Front

Non-included angle

Back

An angle that is not between two legs of a triangle.

Front

Midpoint

Back

The point that divides a segment into two congruent segments.
