Any angle less than 90 degrees is called actue
A right angle is a angle with 90o
An angle of 98 degrees is an obtuse angle
what angle does a hemisphere have what angle does a hemisphere have what angle does a hemisphere have
So basically , you have an right angle and another angle . You draw an right angle over the angle your looking at and if its smaller than the right angle then its an acute angle . If its bigger than the right angle then its a obtuse angle . GoodLuck!(;
No.
Anything less than 90o.
An angle of 72 degrees is acute.
Any angle less than 90 degrees is called actue
if you mean acute then less than 90 degree angle
Yes, as for example 78 degrees and 102 degrees would form a supplementary angle of 180 degrees.
Not if the pentagon is a regular one. Otherwise, several of them can do that.
90
The question appears to relate to the angles of a triangle. 1) If angle 3 is acute then the other two angles can also be acute. In the case of an equilateral triangle all three angles are equal and acute. 2) If angle 3 is acute and one other angle is obtuse then the remaining angle is acute. 3) If angle 3 is acute and one other angle is a right angle then the remaining angle is acute.
Obtuse angles are greater than 90 degrees but less than 180 degrees. Straight angles are exactly 180 degrees. Reflex angles are greater that 180 degrees.
Equilateral, Isosceles, and Scalene If you're talking about the angles though, it can be a right triangle, obtuse triangle, or actue triangle.
A right triangle will always have exactly one right angle and two acute angles. It will never have an obtuse angle. The easiest proof of that is the fact that sum of the angles in a triangle is always 180o, and if it's a right triangle, then one of it's angles is 90o, leaving only 90o for the angles of both of the other two. Since they both have to be greater than zero for it to qualify as a triangle, they will always both be less than ninety, and thus always acute.
