Use the Pythagorean theorem to show that the given points are the vertices of a right triangle. Find the area, A, and the perimeter, P, of the triangle. Give your answers correct to 2 decimal places. (-4, 3), (-8, -5), (2, -10)
A = ?
p = Around 39.10?
This is for something on webassign, so if you could round the answers to two correct decimal places that would fantastic and mucho thanked.
Also, is there a site on which you can make custom triangles on? (Not something like MAtlab where is takes forever to get something going and making an account and something)
