Parallel Lines cut by a transversal

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on opposite sides of the transversal and inside the parallel lines?

Back

Alternate Interior Angles.

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on the same side of the transversal and outside the parallel lines?

Back

Alternate Exterior Angles.

Front

What is the angle relationship when two parallel lines are cut by a transversal and the angles are on the same side of the transversal and inside the parallel lines?

Back

Corresponding Angles.

Front

What is the angle relationship when two lines intersect and form two pairs of opposite angles?

Back

Vertical Angles.

Front

If angle 1 is 44° and angle 2 is a corresponding angle, what is the measure of angle 2?

Back

44°.

Front

If angle 4 is expressed as x + 15 and angle 2 is expressed as 3x - 5, how do you find the value of x?

Back

Set up the equation: x + 15 = 3x - 5 and solve for x.

Front

If angle 6 is 25 degrees, what is the relationship between angle 6 and angle 7 if they are on the same side of the transversal?

Back

Angle 7 is supplementary to angle 6, so angle 7 = 180° - 25° = 155°.

Front

What is the measure of angle D if it is an alternate interior angle to angle 2, which measures 116°?

Back

Angle D = 116°.

Front

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

Back

Corresponding angles are equal.

Front

What is the sum of the measures of the interior angles formed by a transversal cutting through two parallel lines?

Back

The sum is 180° for each pair of consecutive interior angles.
