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

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

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 two angles are supplementary, what is the relationship between them?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If angle 1 = 27°, what is the measure of angle 4 if angle 1 and angle 4 are corresponding angles?

Back

Angle 4 = 27°.

Front

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

Back

Angle 4 = 133°.

Front

What is the measure of an angle if its supplement is 65°?

Back

The measure of the angle is 115°.

Front

If m∠2 = 60° and m∠5 = (x + 25), find the value of x if angles 2 and 5 are corresponding angles.

Back

x = 35.

Front

What are vertical angles?

Back

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