Lesson 1 Angle Relationships (Part 2)

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions on two parallel lines cut by a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines on opposite sides of a transversal. They are equal in measure.

Front

What are Same Side Interior Angles?

Back

Same side interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary, meaning they add up to 180 degrees.

Front

What are Vertical Angles?

Back

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

Front

What are Supplementary Angles?

Back

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

Front

What is 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.

Front

What is the value of X if angle A + angle G = 180 degrees and angle A = 164 degrees?

Back

X = 16 degrees.

Front

If angle 1 and angle 2 are vertical angles, what can be said about their measures?

Back

Angle 1 = Angle 2.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

If two angles are supplementary and one angle measures 90 degrees, what is the measure of the other angle?

Back

The other angle measures 90 degrees.
