An equilateral triangle has three equal sides and three equal angles. Each angle in an equilateral triangle measures 60 degrees.
This is because the sum of all interior angles in any triangle is always 180 degrees. Since all angles in an equilateral triangle are equal, you can calculate the measure of each angle by dividing the total by the number of angles:
180 degrees / 3 angles = 60 degrees per angle.
Thus, every angle in an equilateral triangle is 60 degrees, making it a special type of triangle both in terms of its side lengths and angle measures.
