## Example Questions

← Previous 1

### Example Question #411 : Geometry

What is the measure of an angle complementary to a  angle?

Explanation:

Complementary angles have degree measures that total , so the measure of an angle complementary to a  angle would have measure .

### Example Question #1 : Calculating An Angle Of A Line

What is the measure of an angle congruent to a  angle?

Explanation:

Two angles are congruent if they have the same degree measure, so an angle will be congruent to a  angle if its measure is also .

### Example Question #2 : Calculating An Angle Of A Line

What is the measure of an angle supplementary to a  angle?

Explanation:

Supplementary angles have degree measures that total , so the measure of an angle complementary to a  angle would have measure .

### Example Question #1 : Calculating An Angle Of A Line

What is the measure of an angle that is supplementary to a  angle?

Explanation:

Supplementary angles have degree measures that total , so an angle supplementary to  would measure .

### Example Question #421 : Geometry

What is the measure of an angle congruent to a  angle?

Explanation:

Congruent angles have degree measures that are equal, so an angle congruent to  is

### Example Question #6 : Calculating An Angle Of A Line

What is the measure of an angle that is complementary to a  angle?

Explanation:

Complementary angles have degree measures that total , so an angle complementary to  would measure .

### Example Question #7 : Calculating An Angle Of A Line

What is the measure of an angle that is supplementary to a  angle?

Explanation:

Supplementary angles have degree measures that total . Since we have an  angle, the supplementary angle would measure
