less than 90 degrees
Answer:
The sum of the angles in any triangle are always 180o. By definition an acute triangle is one in which all three angles are acute angles (less than 90o). As soon as one angle becomes 90o (right angled triangle) or greater (obtuse angled) the triangle is no longer acute.

No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.

Is is possible for an isosceles triangle to be an acute triangle?
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
How many acute angles are there in acute triangle?
There are three acute angles in an acute triangle and they add up to 180 degrees.
Do all the angles in an acute triangle have to be different?
No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
