Congruence & Angles Review

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the SSS Triangle Congruence Theorem?

Back

The SSS (Side-Side-Side) Triangle Congruence Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary.

What are corresponding angles?

Back

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

Front

What is the SAS Triangle Congruence Theorem?

Back

The SAS (Side-Angle-Side) Triangle Congruence Theorem states that 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 are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal.

Front

What is the HL Triangle Congruence Theorem?

Back

The HL (Hypotenuse-Leg) Triangle Congruence Theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Front

What is the ASA Triangle Congruence Theorem?

Back

The ASA (Angle-Side-Angle) Triangle Congruence Theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the relationship between same side interior angles?

Back

Same side interior angles are supplementary, meaning their measures add up to 180 degrees.
