Transversal Vocabulary (Part 1)

Front

What are Adjacent Angles?

Back

Adjacent angles are two angles that share a common side and a common vertex, but do not overlap.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.

Front

Define Congruent Angles.

Back

Congruent angles are angles that have the same measure.

Front

What are Supplementary Angles?

Back

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

Front

What are Exterior Angles?

Back

Exterior angles are the angles formed outside of two parallel lines when a transversal crosses them.

Front

What are Interior Angles?

Back

Interior angles are the angles formed inside two parallel lines when a transversal crosses them.

Front

What are Corresponding Angles?

Back

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

Front

What is a Transversal?

Back

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

Front

What is the relationship between Alternate Interior Angles?

Back

Alternate interior angles are the angles that lie between two lines and on opposite sides of a transversal. They are congruent when the lines are parallel.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are the angles that lie outside two lines and on opposite sides of a transversal. They are congruent when the lines are parallel.
