A right angle
Two anlges are complementary if the sum of their degree is 90. So given any angle A less than 90, if angle B is complemenatry its has degree measurement 90-A.
No, the distance of a 45-degree angle is not half of a 90-degree angle. Instead, a 45-degree angle is one-fourth of a full 360-degree rotation and half of a 90-degree angle. In terms of angle measurement, the relationship is that 45 degrees is 50% of 90 degrees, but they are not distances.
Any angular measurement below 90 degrees is an acute angle. Any angular measurement below 90 degrees is an acute angle.
A right triangle has one 90-degree angle.
An 80 degree angle is an acute angle. Any angle measurement that falls below 90 is acute while anything above is obtuse.
greater than 90 less than 180 degree
A 90 degree angle is a right angle.
A 128 degree angle would be an "obtuse" angle. This is because the angle measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
Two complementary angles add up to 90 degrees.If one is 30 degrees, the other has to be a 60 degree angle
An angle that is 87 degrees is an "acute" angle. This is because its measurement are less than 90. Anything above 90 degrees would be considered an "obtuse" angle.
A 90 degree angle is a right angle
