Two angles whose sum is 90 degrees are called complementary angles.
Right angles measure 90 degrees. Angles less than 90 are called acute, and angles greater than 90 are called obtuse. Once you reach 180 degrees, you have formed a straight line. 360 degrees makes a circle.
Angles greater than 90 but less than 180 degrees are obtuse angles Angles greater than 180 but less than 360 degrees are reflex angles
90 degrees and 90 degrees
Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle.Right Angle: An angle whose measure is 90 degrees is called right angle.Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle.Straight Angle: An angle whose measure is 180 degrees called a straight angle.Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle.Complete Angle: An angle whose measure is 360 degrees is called a complete angle.Zero Angle: If the measure of an angle is zero it is called a zero angle.
Angles that measure less than 90 degrees are called acute angles. Right angles measure exactly 90 degrees and obtuse angles are greater than 90 degrees.
Two angles whose sum is 90 degrees are called 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".
Right angles measure 90 degrees. Angles less than 90 are called acute, and angles greater than 90 are called obtuse. Once you reach 180 degrees, you have formed a straight line. 360 degrees makes a circle.
Angles greater than 90 but less than 180 degrees are obtuse angles Angles greater than 180 but less than 360 degrees are reflex angles
90 degrees and 90 degrees
Angles that are less than 90 degrees are acute angles. Angles that are 90 degrees are right angles, and angles that are greater than 90 degrees are obtuse angles.

If you are asking what kind of angles add up to 90 degrees, the answer is complementary angles.
