The hypotenuse of an isosceles right triangle is 14. What is the area of the triangle?
isosceles means each LEG is the same length
Use pythag theorem to find leg length
L^2 + L^2 = 14^2
2L^2 = 196
L^2 = 98
L = sqrt 98 Now area = 1/2 * L * L = 49 units2
45-45-90=x-x-xsqrt(2)
xsqrt(2)=14
x=14/sqrt(2)
x=14sqrt(2)/2
x=7sqrt(2)
area = x*x/2 = 7*7*2 / 2 = 7*7=49
