Transversal Angle Relationships Review

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the sum of the measures of supplementary angles?

Back

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

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.

Front

If m∠7 = 115°, what is m∠2 if they are corresponding angles?

Back

m∠2 = 115°.

Front

If lines A and B are parallel and cut by a transversal, what can be said about the angles formed?

Back

The angles formed have specific relationships such as corresponding, alternate interior, and alternate exterior angles.

Front

How do you find the value of x in angle relationships?

Back

Use the relationships between the angles (e.g., corresponding, alternate interior) to set up equations and solve for x.
