find it using section formula
OpenStudy (kanwal32):
making all sides equal

OpenStudy (kanwal32):
using symmetry and u can verify by taking section formula all sides are equal
OpenStudy (kanwal32):
@jordanjamesbay is it fine

ya
OpenStudy (anonymous):
you can also find it by applying distance formula
OpenStudy (kanwal32):
or making diagnols equal
OpenStudy (kanwal32):
distance formula is section formula
OpenStudy (anonymous):
ya right

Well, the way i would figure this out is quite simple. No formulas or anything.
Plot the points on a coordinate plane.
The, we know all sides of a square are supposed to be equal. So, you should be able to easily see the next point that will make the square equal on all sides.
And, you can go back and count the squares to be sure there equal if needed.
