right angled or othogonal
If you mean "Does the sum of two angles equal exactly 90 degrees?" it is yes.
Complementary angles are two angles that add up to exactly 90 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.
Angles that add to 180 degrees are called supplementary angles, while angles that add to 90 degrees are called complentary angles.
Two angles that add up to 90 degrees are called complementary angles.
Two angles whose sum is 90 degrees are called complementary angles.
Two angles whose sum is 180 degrees are called supplementary angles. When two angles are supplementary, it means that the sum of their measures equals 180 degrees. This relationship is often used in geometry to solve for unknown angles or to identify complementary angles.
The question isn't clear. If the sum of the two angles is 90 degrees, then they're called "complementary angles". If each one is a 90-degree angle, then they're called "two right angles".
Those angles are called complimentary angles. They add up to 90 degrees. Two angles that add up to 180 degrees are called supplementary angles.
Two or more angles that sum to 90 degrees are called complimentary angles.
Two angles that have a sum of 90 degrees are called complementary angles.
