What angles are greater than 90 degree but less than 180 degree?
They are obtuse angles.
Why must a right triangle have two acute 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).
Kinds of angles according to degree?
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
What is the highest degree angle?
180 is a straight line, so all angles have to be less than that.
What is a 40 degree angle?
A 40 degree angle is an acute angle, since all angles less than 90 are acute.
What angles are greater than ninety but less than eighteen?
You mean: What angles are greater than 90, but less than 180. These are obtuse angles
What angles are greater than 90 degree but less than 180 degree?
They are obtuse angles.
What is a triangle that has three angles with all measuring angles greater than zero but less than ninety?
An acute triangle
What does acute angles mean?
An angle less than 90 degree's.
What is the Name for zero degree angle?
an acute angle because it is less than ninety degrees.
Why must a right triangle have two acute 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).
Kinds of angles according to degree?
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
Is a 100 degree angle acute?
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.
What are angles that are measures more than ninety degrees called?
They are called obtuse angles.
A triangle with all angles less than a right angle?
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
What shape can contain no acute angles?
A shape that can contain no acute angles is a rectangle. In a rectangle, all interior angles are right angles, which are exactly 90 degrees. This means there are no angles smaller than 90 degrees, which are considered acute angles. Therefore, a rectangle is an example of a shape that contains no acute angles.
Does an acute triangle have two right angles?
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.
