a right angled triangle is possible in a circle if the hypotenuse is the diameter of the circle

the perimeter is x +y+ d

write y in terms of diameter and x....by using pythagorans theorem

then differentiate and equate to zero ...

you would get the value of x in terms of d

now find the value of y using the found x and d....by pythagoran theorem...

then u will find that y and x are equal....

this is the answer
