90
An angle of 72 degrees is acute.
An acute angle is an angle measuring between 0 and 90 degrees.
Yes, as for example 78 degrees and 102 degrees would form a supplementary angle of 180 degrees.
Acute angles are angles less than 90 degrees an obtuse angles are greater than 90 degrees
Any angle less than 90 degrees is called actue
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.
No.
Anything less than 90o.
if you mean acute then less than 90 degree angle
Not if the pentagon is a regular one. Otherwise, several of them can do that.
yes all scalene triangles are actue. All the angles are 60 degrees. :)
Equilateral, Isosceles, and Scalene If you're talking about the angles though, it can be a right triangle, obtuse triangle, or actue triangle.
