Triangle Congruence Flashcard

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a rule used to determine if two triangles are congruent when two angles and the included side of one triangle are equal to the corresponding parts of another triangle.

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a rule used to determine if two triangles are congruent when two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a rule used to determine if two triangles are congruent when all three sides of one triangle are equal to the corresponding sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a rule used to determine if two triangles are congruent when two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a rule used to determine if two right triangles are congruent when the hypotenuse and one leg of one triangle are equal to the corresponding parts of another triangle.

Front

What is the congruence statement for triangles ABC and DEF if they are congruent by AAS?

Back

The congruence statement is ABC ≅ DEF.

Front

If two triangles are congruent by SSS, what can be said about their corresponding angles?

Back

If two triangles are congruent by SSS, then their corresponding angles are also equal.

Front

What additional information is needed to prove two triangles are congruent by ASA?

Back

You need to know two angles and the included side of one triangle to prove congruence by ASA.

Front

How can you determine if two triangles are congruent using the SSA condition?

Back

SSA does not guarantee congruence; additional information is needed to determine if the triangles are congruent.

Front

What is the significance of the congruence statement in triangle congruence?

Back

The congruence statement indicates that all corresponding sides and angles of the triangles are equal.
