Each interior angle of an equilateral triangle measures 60 degrees
They each measure 60 degrees
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
All angles of an equilateral triangle are congruent, in other words, they all have the same angle measure. Since these three equal angles must add up to 180 degrees, each angle must have the measure of 60 degrees. This is because 60 X 3 = 180 degrees. So, the angles of an equilateral triangle are all equal to 60 degrees. An angle that is less than 90 degrees is an acute angle, and since 60 is less that 90, the angles of an equilateral triangle are acute.
