Front

What is the sum of the interior angles in a triangle?

Back

180 degrees

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle

Front

What does CPCTC stand for?

Back

Corresponding Parts of Congruent Triangles are Congruent

Front

If one angle of a triangle is 60 degrees and another is 62 degrees, what is the measure of the third angle?

Back

58 degrees

Front

What is the SAS postulate?

Back

Side-Angle-Side: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the AAS postulate?

Back

Angle-Angle-Side: 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.

Front

What is the SSS postulate?

Back

Side-Side-Side: If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

What is the included angle in the SAS postulate?

Back

The angle formed between the two sides being compared.
