The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.

A supplementary angle can have any value - depending on the first angle.

Supplementary angles add up to 180 degrees

Supplementary angles total 180 degrees. If you have one angle, subtract it from 180 to find its supplement.

A triangle is a polygonal shape, not an angle and therefore, cannot have a supplementary angle.

The methods are subtraction. -- Subtract an angle from 90Â° to find its complementary angle. -- Subtract an angle from 180Â° to find its supplementary angle.

A supplementary angle will add up to 180 degrees so to find the supplementary angle of 179 degrees, you would take 180-179 to get a 1 degree angle.

The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.

A supplementary angle is the angle which produces a straight line of 180° when added to the given angle. To find the supplementary angle, subtract 84° from 180°. The answer will be 96°.

Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.

Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always

you can use up to 2 angles in a supplementary angle. Just find 2 angles to fit into 180 degrees.

Its supplementary angle is 121 degrees

A supplementary angle can have any value - depending on the first angle.

Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.

Supplementary angles total 180 degrees. If you have one angle, subtract it from 180 to find its supplement.

Supplementary angle = 180 - 84 = 96 degrees.
