LESSON 5 (RIGHT TRIANGLE CONGRUNCE)

Right triangle congruence theorem s

• Hypotenuse-leg (HL) Congruence Theorem

• Hypotenuse-Angle (HA) Congruence Theorem

• Leg-Leg (LL) Congruence Theorem

• Leg-Angle Congruence Theorem

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

Hypotenuse-leg (HL) Congruence Theorem

If the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent

Hypotenuse-angle (HA) Congruence Theorem

If both legs of one right triangle are congruent to the corresponding legs of another right triangle, then the two triangles are congruent

Leg-leg (LL) Congruence Theorem

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

Lag-angle (LA) Congrunce Theorem
