Obtuse angle
An acute angle
A 90-degree angle is commonly called a right angle.
It is a reflex angle that is between 180 and 360 degrees.
An angle measuring 111 degrees is classified as an obtuse angle. In geometry, an obtuse angle is an angle that measures between 90 and 180 degrees. This means that the angle is greater than a right angle (90 degrees) but less than a straight angle (180 degrees).
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
That totals 180.
