Semester Exam Review #2 (Topics 5-8)

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What type of angle pair are ∠1 and ∠3 if they are supplementary?

Back

∠1 and ∠3 are a pair of supplementary angles.

Front

What is the alternate interior angle to angle 3?

Back

The alternate interior angle to angle 3 is angle 5.

Front

How do you find the value of y in angle relationships?

Back

You can find the value of y by using the properties of angles, such as supplementary or complementary relationships.

Front

What is the measure of ∠6 if it is given as 45 degrees?

Back

The measure of ∠6 is 45 degrees.

Front

If lines a and b are parallel, what can be said about the angles formed with a transversal?

Back

When lines a and b are parallel, alternate interior angles are equal, and corresponding angles are equal.

Front

What is the value of x if it is determined by angle relationships?

Back

The value of x can be found using the properties of angles formed by parallel lines and a transversal.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie on opposite sides of a transversal and inside the two lines.

Front

What is the relationship between corresponding angles when two lines are parallel?

Back

Corresponding angles are equal when two lines are parallel.

Front

What is the sum of the measures of angles in a triangle?

Back

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