An obtuse angle is any angle that's measurement is  between 90 and  180 degrees. This type of angle lies in the second quadrant.
By the base angles theorem every equilateral triangle is also equiangular. By the triangle angle sum theorem the three angles add to 180Â°. By the substitution and division properties each of the angles are 60Â°. By the definition of an obtuse angle, none of the angles in an equilateral triangle are obtuse. QED.
