Explanation:
Since we have given that
A(4,0) and B(3,7) are two vertices of right triangle ABC.
The hypotenuse of the triangle is AB.
Construct a rectangle ABCD with AB as its diagonal ,
With the help of A(4,0) and B(3,7) we can find the coordinate of C ,
Since the x-coordinate of A and C will be same and the y-coordinate of B and C will be same ,
So, the coordinate of C becomes (3,0).
Similarly,
Since the x-coordinate of B and D and the y-coordinate of A and D will be same,
But From C and D we will choose C as the third coordinate of Triangle because point C is on the x-axis.
