Angles and Transversals

Front

What are exterior angles?

Back

Exterior angles are the angles formed outside of two parallel lines when they are intersected by a transversal.

Front

What are interior angles?

Back

Interior angles are the angles formed inside two parallel lines when they are intersected by a transversal.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are the angles that lie between two parallel lines on opposite sides of the transversal.

Front

What is the sum of interior angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

If angle <1 measures 143 degrees, what is the measure of angle <4?

Back

37 degrees.

Front

If two angles are supplementary, what is the relationship between their measures?

Back

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

Front

If angle <2 is 90 degrees, what type of angle is it?

Back

It is a right angle.

Front

What is the value of x if angle <3 is 146 degrees and angle <4 is supplementary to angle <3?

Back

34 degrees.

Front

If angle <5 is 61 degrees, what is the measure of its corresponding angle?

Back

61 degrees.
