Transversal Angles

Front

What is a transversal in geometry?

Back

A line that crosses at least two other lines and is used to determine if two lines are parallel.

Front

What are alternate exterior angles?

Back

Angles that lie on opposite sides of the transversal and outside of the parallel lines.

Front

What are corresponding angles?

Back

Angles that lie on the same side of the transversal and in corresponding positions.

Front

What are supplementary angles?

Back

The sum of the angles is 180 degrees. The angles will form a straight line when they share a vertex.

Front

What are complementary angles?

Back

The sum of the angles is 90 degrees. They will form a right angle when there is a common vertex.

Front

How can you determine if two lines are parallel using a transversal?

Back

If the alternate interior angles are equal, then the two lines are parallel.

Front

What is the relationship between corresponding angles when two lines are cut by a transversal?

Back

If the corresponding angles are equal, then the two lines are parallel.

Front

What is the sum of the interior angles on the same side of the transversal?

Back

The sum is 180 degrees, which means they are supplementary.

Front

What is the definition of vertical angles?

Back

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

Front

What is the relationship between alternate interior angles?

Back

If the alternate interior angles are equal, then the lines are parallel.
