HW 6.6 Triangle Congruence Flashcardizz

Front

What is the AAA triangle congruency theorem?

Back

AAA (Angle-Angle-Angle) is NOT a triangle congruency theorem because it only shows that triangles are similar, not congruent.

What does the Hypotenuse-Leg (HL) theorem state?

Back

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

What information is needed to prove triangles are congruent by Angle-Side-Angle (ASA)?

Back

You need two angles and the side between them to be equal in both triangles.

What is the Side-Side-Side (SSS) congruence postulate?

Back

The SSS postulate states that if all three sides of one triangle are equal to the three sides of another triangle, then the triangles are congruent.

What does the Side-Angle-Side (SAS) theorem state?

Back

The SAS theorem states that if two sides and the angle between them in one triangle are equal to two sides and the angle between them in another triangle, then the triangles are congruent.

What is the Angle-Angle-Side (AAS) theorem?

Back

The AAS theorem states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

How can you determine if two triangles are congruent?

Back

You can determine if two triangles are congruent by using congruence theorems such as SSS, SAS, ASA, AAS, or HL.

What is the significance of the Hypotenuse-Leg (HL) theorem in right triangles?

Back

The HL theorem is significant because it provides a quick way to prove the congruence of right triangles using only two pieces of information.

Front

What does it mean if two triangles are similar?

Back

If two triangles are similar, it means they have the same shape but not necessarily the same size; their corresponding angles are equal, and their sides are in proportion.
