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

Back

Hypotenuse Leg Congruence Theorem

Front

If the shorter legs of two right triangles are congruent, then the triangles are congruent.

Back

Leg Leg Congruence Theorem

Front

If the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.

Leg Angle Congruence Theorem

Front

Line segment connecting a point outside a circle to a point of tangency.

Back

tangent segment

Front

Two tangent segments from the same exterior point of a circle are congruent.

Back

Tangent Segment Theorem

Front

Circles in the same plane that intersect at one point.

Back

tangent circles

If one pair of opposite sides of a quadrilateral is congruent and parallel, then it is a:

Parallelogram/Congruent-Parallel Side Theorem

Front

Angles of a trapezoid sharing a base.

Back

base angles of a trapezoid

Front

Midsegment connecting trapezoid legs is parallel to bases; its length is half the sum of the bases' lengths.

Back

Trapezoid Midsegment Theorem

Front

If a circle’s diameter is perpendicular to a chord, then it bisects the chord and the arc determined by the chord.
