Transversals

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define consecutive (same side) interior angles.

Back

Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

Front

What are vertical angles?

Back

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

Front

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

Back

180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about alternate exterior angles?

Back

They are equal.

Front

What is the equation to solve for x if 12X - 29 + 4X + 1 = 180?

Back

x = 13.

Front

What type of angles are ∠2 and ∠6 if they are corresponding?

Back

They are equal.

Front

What is the definition of supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

How do you identify alternate interior angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two lines.
