The square is centered about the origin.
The vertex makes an angle of 45 degrees to the x-axis so it lies on the line y=x
.
.
Substituting,
x%5E2%2By%5E2=25
x%5E2%2Bx%5E2=25
2x%5E2=25
x%5E2=25%2F2
x=5%2Fsqrt%282%29
y=%285sqrt%282%29%29%2F2
So the coordinates are,
(%28+5sqrt%282%29%29%2F2+,%285sqrt%282%29%29%2F2)
(%28-5sqrt%282%29%29%2F2,%285sqrt%282%29%29%2F2)
(%28-5sqrt%282%29%29%2F2,%28-5sqrt%282%29%29%2F2)
(%285sqrt%282%29%29%2F2,%28-5sqrt%282%29%29%2F2)
