Triangle Congruence Flashcard

Front

What does SAS stand for?

Back

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

Front

What is the ASA rule in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion used to determine if two triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

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

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 first statement in the reason column of a proof?

Back

The first statement is always 'Given', which states the information provided in the problem.

Front

What is the Vertical Angles Theorem?

Back

The Vertical Angles Theorem states that when two lines intersect, the opposite (or vertical) angles are equal.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal parts.

Front

What does the Alternate Interior Angles Theorem state?

Back

The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the alternate interior angles are equal.

Front

What is the definition of the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.
