What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

Front

What is the sum of the angles in a straight line?

Back

The sum of the angles in a straight line is 180°.

Front

What is the measure of a right angle?

Back

A right angle measures 90°.

Front

What is the Transitive Property in geometry?

Back

The Transitive Property states that if angle A is congruent to angle B, and angle B is congruent to angle C, then angle A is congruent to angle C.

Front

What are Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What is a Linear Pair of Angles?

Back

A Linear Pair of Angles consists of two adjacent angles that form a straight line, and their measures add up to 180°.

Front

What is the definition of Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie on opposite sides of the transversal and inside the two lines.

Front

What is the definition of Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie on opposite sides of the transversal and outside the two lines.
