What is the measure of angle HJG in degrees?

Back

67º

Front

What additional information is required for two triangles to be congruent by SSS?

Back

The lengths of all three sides of both triangles must be known.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence.

Front

What is the measure of angle ACD in degrees?

Back

121º

Front

What is the criterion for triangle congruence if two sides and the included angle are known?

Back

The triangles are congruent by SAS.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the SSS criterion for triangle congruence?

Back

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

Front

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

Back

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 by ASA.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint, called the vertex.

Front

What is the relationship between the angles in a triangle?

Back

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