What is equilateral triangle?
A particular kind of geometric figure with three equal-length sides and three equal-measure angles is called an equilateral triangle. Put differently, an equilateral triangle has three congruent sides and three congruent angles.
An equilateral triangle has three equal angles, each measuring sixty degrees, and the sum of its interior angles is always 180 degrees. A particular subset of triangles known as equilateral triangles have symmetry characteristics that distinguish them from other triangles in terms of both sides and angles.
