There is no special name for a 120º angle.
obtuse
An angle from 181 degrees to 359 degrees is called a reflex angle. A reflex angle is an angle that measures greater than 180 degrees but less than 360 degrees. It is formed by rotating a ray less than one full revolution, resulting in an angle that extends beyond a straight line.
The 4 classifications are:- 1 Acute angle which is greater than 0 but less than 90 degrees 2 Right angle which is 90 degrees 3 Obtuse angle which is greater than 90 but less than 180 degrees 4 Reflex angle which is greater than 180 but less than 360 degrees A full rotation is 360 degrees
Congruent angles have the same measure. congruent Kenpachi54 improve answer: Actually, angles don't have to be congruent just to have the same angle measurements A has a right angle is 90 degrees. even if there is a small right angle and a large right angle you know they are both 90 degrees because ALL right angles are 90 degrees, so there is really no name for it.
This type of angle is called a 'revoloution angle'.
The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees.
An angle consists of two rays or lines having the same endpoint (vertex). An angle is formed when two rays meet at an endpoint. The endpoint is called the vertex of the angle. The measure of an angle tells how far one side is turned from the other side -0 degrees is no turn and 360 degrees is one full turn. You can name angles by how their measures compare to 90 degrees or 180 degrees. There are 4 types of angles, acute angle, right angle, obtuse angle, and straight angle. An acute angle is an angle that measures less than 90 degrees. A right angle is an angle that measures exactly 90 degrees. A straight angle measures exactly 180 degrees.
