Parallel Lines Cut by a 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 equation to solve for X when parallel lines are cut by a transversal?

Back

12X - 29 + 4X + 1 = 180

Front

What are Alternate Interior Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

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

Front

What are Corresponding Angles?

Back

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

Front

Identify the pair of angles that are Alternate Exterior Angles: Angle 7 and Angle 4, Angle 2 and Angle 6, Angle 8 and Angle 1, Angle 2 and Angle 8.

Back

Angle 8 and Angle 1

Front

If m∠C = 116°, what is the measure of angle C?

Back

∠C = 116°

Front

What is the relationship between Alternate Interior Angles?

Back

Alternate interior angles are equal when the lines are parallel.

Front

What is the sum of the angles on a straight line?

Back

The sum of the angles on a straight line is 180°.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.
