Proving Right Triangles Congruent(Section 4-5 lab)

Front

What does HA stand for in triangle congruence?

Back

HA stands for Hypotenuse-Angle, a method used to prove right triangles congruent.

Front

What does LA stand for in triangle congruence?

Back

LA stands for Leg-Angle, a method used to prove right triangles congruent.

Front

What does LL stand for in triangle congruence?

Back

LL stands for Leg-Leg, a method used to prove right triangles congruent.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a method used to prove right triangles congruent.

Front

What is the SSS postulate?

Back

SSS stands for Side-Side-Side, a postulate that states if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the SAS postulate?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the ASA postulate?

Back

ASA stands for Angle-Side-Angle, a postulate that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is CPCTC?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent, a principle used after proving triangles congruent.

Front

Which methods can be used to prove right triangles congruent?

Back

HA, LA, LL, and HL can all be used to prove right triangles congruent.

Front

What is the significance of the HL theorem?

Back

The HL theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.
