Geometry L Unit 5 - Triangle Congruence

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 the SSS criterion?

Back

To determine if two triangles are congruent using the SSS criterion, measure the lengths of all three sides of both triangles. If all three pairs of corresponding sides are equal, the triangles are congruent.

Front

How can you determine if two triangles are congruent using the SAS criterion?

Back

To determine if two triangles are congruent using the SAS criterion, measure two sides and the included angle of both triangles. If the two sides and the included angle of one triangle are equal to the corresponding parts of the other triangle, the triangles are congruent.

Front

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

Back

To determine if two right triangles are congruent using the HL criterion, measure the lengths of the hypotenuse and one leg of both triangles. If both the hypotenuse and the leg of one triangle are equal to the hypotenuse and leg of the other triangle, the triangles are congruent.

Front

What is the sum of the angles in any triangle?

Back

The sum of the angles in any triangle is always 180 degrees.

Front

If one angle of a triangle measures 46 degrees, what is the sum of the measures of the other two angles?

Back

The sum of the measures of the other two angles would be 180 degrees - 46 degrees = 134 degrees.

Front

In triangle congruence, what is the importance of corresponding parts?

Back

In triangle congruence, corresponding parts are important because they must be equal for the triangles to be considered congruent. This includes corresponding sides and angles.

Front

What is the relationship between congruent triangles and their corresponding sides and angles?

Back

Congruent triangles have equal corresponding sides and equal corresponding angles.
