parallel lines (matching angles)

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines; they are equal when the lines are parallel.

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines; they are equal when the lines are parallel.

Front

What are Consecutive Interior Angles?

Back

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

Front

If angle 1 and angle 2 are corresponding angles, what can we say about their measures?

Back

Angle 1 = Angle 2 when the lines are parallel.

Front

If angle 3 and angle 4 are alternate interior angles, what can we conclude?

Back

Angle 3 = Angle 4 when the lines are parallel.

Front

What is the sum of the measures of consecutive interior angles?

Back

180 degrees when the lines are parallel.

Front

If two angles are supplementary and one is 33 degrees, what is the measure of the other angle?

Back

147 degrees.

Front

What is the equation to find x if 33 = 7x + 5?

Back

x = 4.
