11D Angles formed by Parallel Lines and a Transversal

Front

What is the definition of alternate exterior angles?

Back

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

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 supplement of an angle?

Back

The supplement of an angle is the amount by which it falls short of 180 degrees.

Front

If angle 6 is 25 degrees, what is the measure of angle 7 if they are same-side interior angles?

Back

Angle 7 is 155 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are congruent, meaning they have the same measure.

Front

If angle 1 = 3x - 4 and angle 3 = 5x - 38, how do you find the measure of angle 4?

Back

Set angle 1 equal to angle 3 and solve for x, then substitute x back to find angle 4.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie on the same side of the transversal and between the two parallel lines.

Front

If angle 5 is 90 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 90 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If the measure of angle 2 is 70 degrees, what is the measure of angle 4 if they are alternate interior angles?

Back

Angle 4 is also 70 degrees.
