Monday- 11/18 CPCTC Practice with Algebra

Front

What does CPCTC stand for in geometry?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is a principle used to prove that corresponding angles and sides of congruent triangles are equal.

Front

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

Back

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

Front

If two triangles are congruent, what can be said about their corresponding sides and angles?

Back

If two triangles are congruent, their corresponding sides are equal in length, and their corresponding angles are equal in measure.

Front

How can you determine if two triangles are congruent using angle-side-angle (ASA) criteria?

Back

Two triangles are congruent by ASA if two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

Front

What is the relationship between the angles of a triangle and the exterior angle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the significance of the notation '∆' in geometry?

Back

The notation '∆' represents a triangle in geometry.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

The SSS criterion states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

How do you find the measure of an unknown angle in a triangle when two angles are known?

Back

To find the measure of an unknown angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the Angle-Angle (AA) similarity criterion?

Back

The AA criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.
