They are obtuse angles.
A right angle must have two acute angles because since one angle is ninety degrees, than the other two must equal ninety degrees. To make ninety degrees with two angles, both of them must be acute, or less than 90 degrees (each).
They are as follows:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
180 is a straight line, so all angles have to be less than that.
A 40 degree angle is an acute angle, since all angles less than 90 are acute.
You mean: What angles are greater than 90, but less than 180. These are obtuse angles
They are obtuse angles.
An acute triangle
An angle less than 90 degree's.
an acute angle because it is less than ninety degrees.
A right angle must have two acute angles because since one angle is ninety degrees, than the other two must equal ninety degrees. To make ninety degrees with two angles, both of them must be acute, or less than 90 degrees (each).
They are as follows:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
A 100 degree angle is NOT an acute angle, it's an obtuseangle.Acute angles are less than 90 degrees, Obtuse angles are greater than 90 degress.
They are called obtuse angles.
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
180 is a straight line, so all angles have to be less than that.
No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.
