IP--Transversals and Angles Pairs

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines.

Front

What is a linear pair of angles?

Back

Two adjacent angles that form a straight line and are supplementary.

Front

Define corresponding angles.

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

They are equal.

Front

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

Back

They are supplementary.

Front

If angle 1 = 27°, what is the measure of angle 3 if they are a linear pair?

Back

Angle 3 = 153°.

Front

If angle 4 and angle 8 are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

What is the measure of angle 2 if angle 1 = 27° and they are vertical angles?

Back

Angle 2 = 27°.

Front

If lines m and l are parallel and angle A = 82°, what is the measure of angle B if they are corresponding angles?

Back

Angle B = 82°.
