Isosceles! If right triangle has a 45 degree angle, then the other angle not 90 degrees is also 45 degrees. Two sides are equal, too. This triangle is half a square.
Let s be length of the legs and let h be the hypotenuse.
Area, A=(1/2)s^2, meaning
The two length s meet at the right-angle.
, ... and you do the steps,...
Perimeter is the sum of the lengths that make the triangle.
Perimeter is
