Angles Lesson and Practice

Adjacent Angles

are "next to" each other
share a common vertex
share a common side

Multiple Choice

These two angles are adjacent to each other. Calculate the missing measurement.

85 degrees

90 degrees

25 degrees

45 degrees

Multiple Choice

These two angles are adjacent to each other. What is the measure of angle A?

45^o

160^o

30^o

35^o

Complementary Angles

2 angles whose sum is 90 degree

Multiple Choice

What is an example of a pair of complementary angles?

13° and 45°

10° and 170°

81° and 9°

90° and 3°

Multiple Choice

These two angles are complementary since they show the right angle symbol. Find the missing angle.

Supplementary Angles

2 angles whose sum is 180 degrees
2 angles that form a straight line

Multiple Choice

2 angles are supplementary. One angle measures 48 degrees. What is the measure of the other angle?

142

132

Vertical Angles

vertical angles are across from each other
vertical angles are always equal to each other

Multiple Choice

Are these vertical angles?

yes

Multiple Choice

Are these vertical angles (yes/no)

yes

Multiple Choice

Are these Vertical Angles?

yes

Multiple Choice

What is the measure of the missing angle

133

180

Multiple Choice

Since these two angles form a right angle which is 90 degrees. Use the equation 5x +25 + x + 5=90 and solve for x by combining like terms

Multiple Choice

What is the value of "x"?

Since the two angles total 180 degrees, we can write and solve the equation 3x + 123 =180

Multiple Choice

Since these are vertical angles and they are equal, use the equation 6x + 20 = 140 and solve for x

140

Multiple Choice

Write an equation and find the value of x

6x + 12 + 3x - 3= 90

x = 9

6x +12 + 3x -3 = 180

x = 55

6x +12 +3x -3 = 180

x =19

Multiple Choice

Tell whether the angles are complementary or supplementary. Then find the value of x.

Complementary; x=25

Complementary; x=5

Supplementary; x=25

Supplementary; x=5

Multiple Choice

Write an equation and Solve for x

12x + 25 = 85 x=5

12x + 25 + 85 = 180

x=10

12x + 25 + 85 = 90

x =25
