An angle of ore than 90 degrees but less then 180 degrees is called an obtuse angle. There is no specific name for 91 degrees.
acute
an acute angle because it is less than ninety degrees.
An angle which measure exactly 90 degrees is called a right angle.
The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees.
That is a straight angle.
Ninety degrees. The name comes (I think) from the fact that one angle of a square is ninety degrees. Or in the case of all 4 right angles added together the sum would be 360 degrees.
It's called an acute angle, greater than 90 degrees is an obtuse angle. what about if it is 91 degrees would it still be named obtuse?
This type of angle is called a 'revoloution angle'.
Yes, angles between 90 and 180 degrees are called obtuseangles.On the other hand, there is no reason why an angle of exactly 100 degrees should have a special name. There is nothing special about this particular angle.
Acute angle: greater than 0 but less than 90 degrees Right angle: exactly 90 degrees Obtuse angle: greater than 90 but less than 180 degrees Reflex angle: greater than 180 but less than 360 degrees
I think you're asking the name of an angle like this \_ rather than an angle like this /\. If so, the first is obtuse (more than 90 degrees) and the second is acute (less than 90 degrees). Incidentally, an angle of exactly 90 degrees, like this _| is called a right angle.
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.
