A triangle is when three sides are equal in area and all three sides are perpendicular to each other. The law of triangle states that if a triangle has three equal sides, then the third side is also equal in area.
In a simple triangle, all sides are equally long and the hypotenuse is the shortest side. In a triangle with three equal sides, the hypotenuse is the longest side.
