Special Angles: Transversals

Front

What are special angles formed by two parallel lines cut by a transversal?

Back

Corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always congruent.

Front

What are corresponding angles?

Back

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

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are congruent when two parallel lines are cut by a transversal.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are congruent when two parallel lines are cut by a transversal.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

If two angles are supplementary, what is their relationship?

Back

Supplementary angles add up to 180 degrees.

Front

What is the value of x if angle 5 is 45 degrees and angle 6 is supplementary to angle 5?

Back

x = 135 degrees.
