Triangle Congruence Theorems

Triangle congruence theorems establish criteria for determining whether two triangles are congruent, meaning they have the same size and shape.

SSS (Side-Side-Side) Theorem, Triangle congruence sss sas asa aas hl worksheet answer key

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

Example: If triangle ABC has sides AB = 5 cm, BC = 7 cm, and AC = 10 cm, and triangle DEF has sides DE = 5 cm, EF = 7 cm, and DF = 10 cm, then triangle ABC is congruent to triangle DEF.

SAS (Side-Angle-Side) Theorem

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

Example: If triangle ABC has AB = DE, BC = EF, and angle B is congruent to angle E, then triangle ABC is congruent to triangle DEF.

ASA (Angle-Side-Angle) Theorem

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

Example: If triangle ABC has angle A congruent to angle D, angle B congruent to angle E, and side AB = DE, then triangle ABC is congruent to triangle DEF.

AAS (Angle-Angle-Side) Theorem

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

Limitations:The AAS theorem is only applicable if the non-included side is opposite the congruent angles.

Example: If triangle ABC has angle A congruent to angle D, angle B congruent to angle E, and side AC = DF, then triangle ABC is congruent to triangle DEF.

HL (Hypotenuse-Leg) Theorem

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

Relevance to Right Triangles:The HL theorem is only applicable to right triangles, where the hypotenuse is the longest side.

Example: If triangle ABC is a right triangle with AB (hypotenuse) = DE (hypotenuse) and BC (leg) = EF (leg), then triangle ABC is congruent to triangle DEF.
