Vertical Lines and Linear Pairs

Front

What is a Linear Pair?

Back

A Linear Pair is a pair of adjacent angles whose non-common sides form a straight line. The sum of the angles in a linear pair is always 180°.

What are Vertical Angles?

Back

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

If m∠4 = 150°, what is m∠1 if ∠1 and ∠4 are a Linear Pair?

Back

m∠1 = 30° (Linear Pairs are supplementary, so 180° - 150° = 30°).

What are Corresponding Angles?

Back

Corresponding Angles are angles that are in the same position on two parallel lines cut by a transversal. They are congruent.

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles on opposite sides of a transversal but inside the two lines. They are congruent when the lines are parallel.

What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.
