An equilateral triangle has 3 interior equal acute angles each measuring 60 degrees.
In general an acute angle is greater than 0 but less than 90 degrees.

An equilateral triangle must be acute because each angle is equal to 60 degrees. If all three angles are less than 90 degrees then a triangle is acute.
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.
Yes . Triangle have right acute and obtuse angle except compelete angle.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- Right angle triangle:a 90 degree angle and 2 acute angles Scalene triangle: 3 acute angles Obtuse triangle: an obtuse angle and 2 acute angles Isosceles triangle: 2 equal base angles and an apex angle Equilateral triangle: 3 equal angles each measuring 60 degrees
Each of the interior angles of an equilateral triangle is 120 degrees.
