The hypotenuse of a right triangle measures 6 inches and one angle is 45 degrees. What is the number of square inches in the area of the triangle?

Both of the other angles must be 45o        so each leg is the same length

 

pythag theorem    62 =  L2 + L2

                             36 = 2L2         L = sqrt (18)       Area = 1/2 b * h =   1/2 (sqrt18)(sqrt(18) ) = 9 in 2
