A triangle (or other polygon) on a concave surface (such as the inside of a sphere), possibly.
Two angles whose sum is 90 degrees are called complementary angles.
They are supplementary angles
Two angles whose sum is 180 degrees are supplementary. If it is 90 degrees then they are complementary.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
It is a plane six-sided figure, each of whose sides is of length s units and each of whose interior angles is 120 degrees.
Two angles the sum of whose measures is 90 degrees are complimentary angles.
Two angles whose sum is 90 degrees are called complementary angles.
180 degrees
Two angles whose sum is 90 degrees are called complementary angles. Two angles whose sum is 180 degrees are called supplementary angles. A single angle of 90 degrees is called a right angle.
supplementary angles
two angles whose sum is 90 degrees is a complementary angle.
They are supplementary angles
Supplementary angles have a sum of 180 degrees.
complementary angles are two angles whose total degrees adds up to 90o supplementary angles are two angles whose total degrees adds up to 180o
The angles are complimentary when they add to 90 degrees.
Two angles whose sum is 180 degrees are supplementary. If it is 90 degrees then they are complementary.
Complementary angles add up to 90 degrees
