Question

When 3 coordinates of square are given how to find 4th coordinate

Answer 1

by applying distance formulae you can find the coordinates ofsquares.. hope it helps you dear

Answer 2

Hii friend,

Let ABCD be a square.

And,

Let A(X1,Y1) , B(X2,Y2) , (X3,Y3) be the three given vertices of a square and let it's fourth vertex be D(a,b) .

Join AC and BD.

Let AC and BD intersect at the point O.

We know that the diagonals of a square are equal.

Then,

Find the Length of AC and BD by using distance formula.

AC = BD [ Diagonals are equal]

PUT ALL THE VALUES OF VERTICES OF SQUARE AND THEN SOLVE U WILL GET THE COORDINATES OF FOURTH VERTICES OF THE SQUARE...

HOPE U GOT IT... ;-)
