It also follows from this that the perimeter of the medial triangle equals the semiperimeter of triangle ABC , and that the area is one quarter of the area of triangle ABC .

The area of a triangle is half of the area of the rectangle with equivalent base and height.

If , , and are the lengths of the sides of the triangle, then the triangle inequality states that formula_1with equality only in the degenerate case of a triangle with zero area.

In geometry, a Heronian triangle is a triangle that has side lengths and area that are all integers.
