An angle which measures exactly 90 degrees is called a "right" angle. (One measuring less than 90 is 'acute', and one measuring more than 90 degrees is 'obtuse'.)
An angle which measure exactly 90 degrees is called a right angle.
a right angle is formed because the angle measures 90 degrees
A 90-degree angle is also referred to as a right angle.
A right angle measures 90 degrees
It's an acute angle since it is under 90 degrees. An angle larger than 90 degrees is an obtuse angle.
A right angle is exactly 90 degrees.
An angle that measures to precisely 90o is called a right angle.
An angle is 90 degrees if and only if it is a right angle.
It has usually a red box at the vertex and is called a "right angle."
a right angle
If it measures 90 degrees, then it is called a right angle.
A right angle
There are typically 3 angles, obtuse, acute, and right. obtuse- an angle that measures over 90° acute- an angle that measures less than 90° right- an angle that measures exactly 90°
An angle that measures more than 90 degrees is called an obtuse angle.
