to calculate things related to a right triangle.
Notes about right triangles:
The base b, height h and single right angle define the right triangle.
You can get help figuring out other things about right triangles, here.
The area of a right triangle is ^{1}/_{2} × base × height, or ^{1}/_{2}bh.
The perimenter of a right triangle is b+h+(b^{2}+h^{2})^{1/2}.
