Angle Relationships

Find the measure of the exterior angle . (What is ?)

• 91°

• 81°

• 89°

• 109°

Vertical angles are always

• acute.

• a total of 180 degrees.

• congruent.

• adjacent.

Supplementary angles always add up to

• True

• False

The following two parallel lines that have been cut by a transversal.

If angle 7 measures 118 degrees, what is the measure of angle 5?

• 118

• 62

• 180

• 298

∠1 and ∠3 can best be described as -

• complementary angles
• supplementary angles
• vertical angles
• adjacent angles

• The value of x is 79, because the two angles shown in each diagram are congruent

• The value of x is 79, because the two angles shown in each diagram are supplementary

• The value of x is greater than 90, because the two angles shown in each diagram are obtuse angles.

• The value of x is 11, because the two angles shown in each diagram are complementary

Determine the measure of angle w.

• w =75, because 45 + 60 = 105 and 180 -105 =75

• w = 105, because 180-(45+60) = 75 and 180 - 75 = 105

• w = 285, because 45+60 = 105 and 105 + 180 = 285

• w= 165, because 180-60 = 120 and 120 + 45 = 165

Determine the measure of angle B.

• 82°

• 98°

• 180°

• 8°
