Angle Relationships

Front

What is the definition of Alternate Exterior Angles?

Back

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

Front

What is the definition of Vertical Angles?

Back

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

Front

What is the definition of Corresponding Angles?

Back

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

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal.

Front

If two angles are supplementary, what is their relationship?

Back

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

Front

If Angle 1 and Angle 2 are Alternate Exterior Angles, what can be said about their measures?

Back

If Angle 1 and Angle 2 are Alternate Exterior Angles, then they are equal in measure.

Front

What is the relationship between Angle 2 and Angle 4 if they are Vertical Angles?

Back

If Angle 2 and Angle 4 are Vertical Angles, then they are equal in measure.

Front

How do you find the value of x if Angle 1 + Angle 2 = 180 degrees and Angle 1 = 65 degrees?

Back

x = 180 - 65 = 115 degrees.

Front

What is the relationship between Corresponding Angles when two parallel lines are cut by a transversal?

Back

Corresponding Angles are equal when two parallel lines are cut by a transversal.

Front

What is the sum of the measures of two angles that are Vertical Angles?

Back

The sum of the measures of two Vertical Angles is always equal to 360 degrees.
