4.2.2 Triangle Congruence: ASA, AAS, and HL

Question 1

included side

Answer 1

it is the common side of two consecutive angles in a polygon

Question 2

Angle-Side-Angle (ASA) Congruence Postulate

Answer 2

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.

Question 3

Angle-Angle-Side (AAS) Congruence Theorem

Answer 3

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

Question 4

Hypotenuse-Leg (HL) Congruence Theorem

Answer 4

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