What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent (equal in measure).

What does the Vertical Angles Theorem state?

Front

What is the definition of an inverse statement?

Back

An inverse statement negates both the hypothesis and conclusion of a conditional statement. For example, the inverse of 'If P, then Q' is 'If not P, then not Q.'

Front

What is the measure of angle A if it is given as 44 degrees?

Back

Angle A measures 44 degrees.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is a converse statement?

Back

A converse statement is formed by reversing the hypothesis and conclusion of a conditional statement. For example, the converse of 'If P, then Q' is 'If Q, then P.'

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the definition of a linear pair?

Back

A linear pair is a pair of adjacent angles formed when two lines intersect. The angles in a linear pair are supplementary, meaning they add up to 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
