GEO 4.2 Transversal Angles Classwork

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

How many pairs of vertical angles are formed when two lines intersect?

Back

There are 4 pairs of vertical angles formed when two lines intersect.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others. They are equal in measure.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of the transversal and outside the two lines. They are equal in measure.

Front

What are supplementary angles?

Back

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

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal to each other.

Front

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

Back

The corresponding angles are equal.

Front

If angle 1 is 70 degrees, what is the measure of angle 7 if they are corresponding angles?

Back

Angle 7 is also 70 degrees.

Front

What is the sum of the measures of two supplementary angles?

Back

The sum of the measures of two supplementary angles is 180 degrees.
