Unit 3 Assessment - RECOVERY TEST - PART 1 (G-G.CO.C.9)

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

Define 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 is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line. The sum of the angles in a linear pair is 180 degrees.

Front

What are vertical angles?

Back

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

Front

If angle 4 is 50 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 50 degrees because corresponding angles are equal.

Front

How do you find the measure of an angle if you know its linear pair?

Back

To find the measure of an angle in a linear pair, subtract the known angle from 180 degrees.

Front

What is the relationship between congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

If angle 5 is 130 degrees, what is the measure of angle 6 if it is NOT congruent to angle 5?

Back

Angle 6 can be any measure other than 130 degrees.

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.

Front

If angle 7 is 50 degrees, which angle is NOT congruent to it?

Back

Angle 8 is NOT congruent to angle 7 if angle 8 has a different measure.
