SAS, SSS, HL

Front

What does SSS stand for in triangle congruence?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence stating that 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 does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for triangle congruence applicable to right triangles, stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

How can you determine if two triangles are congruent using SSS?

Back

Check if all three corresponding sides of the triangles are equal.

Check if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

How can you determine if two right triangles are congruent using HL?

Back

Check if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle.

What is the significance of the included angle in SAS?

Back

The included angle is the angle formed between the two sides being compared; it must be equal for the triangles to be congruent.
