### An equilateral triangle is a specific type of triangle where all three sides are equal in length

An equilateral triangle is a specific type of triangle where all three sides are equal in length. Equilateral triangles have several key properties:

1. Equal Angles: Each angle in an equilateral triangle measures 60 degrees. Therefore, the sum of the three angles is always equal to 180 degrees.

2. Symmetry: Equilateral triangles possess rotational symmetry of order 3, which means that you can rotate the triangle 120 degrees in either direction and it will still look the same.

3. Congruent Sides: Since all three sides are equal, any two angles opposite the equal sides are also congruent. This property allows for the creation of various geometric constructions and calculations within equilateral triangles.

4. Height and Area: The height of an equilateral triangle is the perpendicular distance between one of the vertices and the opposite side. The height divides the triangle into two congruent right triangles, and its length can be found using the Pythagorean theorem, where h = (√3/2) * s, where “s” represents the length of each side.

Similarly, the area of an equilateral triangle can be calculated using the formula A = (s^2 * √3) / 4, where “A” represents the area and “s” is the length of each side.

It is important to note that equilateral triangles are a special case of isosceles triangles, which have at least two sides of equal length. However, equilateral triangles take this to the next level by having all three sides equal in length.
