I have a more easy way to do this ... Consider sir's diagram quadrilateral PQRS as angles P,Q,R are 90 as per question then angle S must be 90 . Now observe that PQRS is a cyclic quad whose diagonals intersect at suppose T now we know diagonal of square bisect each other so I write midpoint of PQ as I know parametric cordinate if both P and Q now suppose S is (h,k) midpoint is also (X1+h/2,y1+k/2) now compare the two midpoint as they are the same eliminate Alfa beta you get what you want

Sir if I'm correct I want a 📌 as this method can save time. It became lengthy as I explained all the steps
