11D Angles formed by Parallel Lines and a Transversal

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. They are equal in measure.

Front

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

Back

Alternate interior angles are equal in measure when two parallel lines are cut by a transversal.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If angle 1 and angle 2 are supplementary, what is the relationship between their measures?

Back

The measures of angle 1 and angle 2 add up to 180 degrees.

Front

What is the measure of angle 4 if angle 1 = 27°?

Back

Angle 4 = 27° (since angle 1 and angle 4 are corresponding angles).

Front

If angle P measures 60 degrees, what is the measure of angle C if they are alternate interior angles?

Back

Angle C = 60° (since alternate interior angles are equal).

Front

Solve for x: Angle 4 = x + 15, Angle 2 = 3x - 5. What is the value of x?

Back

x = 10.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal in measure.

Front

If angle 1 = 3x - 4 and angle 3 = 5x - 38, find the measure of angle 4.

Back

Angle 4 = 133°.

Front

What are alternate exterior angles?

Back

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