The corner of a square measures 90 degrees which is a right angle.

A right angle measures 90 degrees
A right angle is a 90 degree angle.
Any triangle with a 90 degree angle is classified as a right triangle.
Two angles that have measures summing to 90 degrees are called complementary angles. For example, a 30-degree angle and a 60-degree angle are complementary because 30 + 60 = 90. Another pair could be a 45-degree angle and a 45-degree angle, which also add up to 90 degrees.
Every triangle with sides of 6 in, 8 in and 10 in will have a 90 degree angle.
the latitude of the north pole is 90 degrees N,and the latitude of the south pole is 90 degrees S and because each parallel measures one degree north or south of the equator.
A right triangle because the 90 degree angle creates a corner.
A combination square
A right angle measures 90 degrees.
A right angle triangle always has a 90 degree angle and two acute angles which altogether add up to 180 degrees.
An angle measuring 55 degrees is an acute angle since it is measures less than 90 degrees.
