Height of an equilateral triangle

An equilateral triangle is a triangle in which all sides are equal. Also, the heights drawn from any vertex are also equal. All angles are equal to 60 degrees. The straight lines that form a triangle are the sides, and their points of contact are the vertices. One of the segments that runs parallel to the horizontal plane is called the base.
