An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.

An acute triangle is also known as a scalene triangle that has 3 sides of different lengths and 3 interior acute angles of different sizes
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.
An acute polygon is one whose interior angles are all acute. Only a triangle can be an acute polygon.
-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.
No, because a right triangle has one angle which is 90 degrees, and the definition of an acute triangle says that each of the 3 angles of the triangles must be less than 90 degrees.
