Show that there is a C point to these points A(-2|2|3), B(2|10|4) and D(5|-2|7), so that the quadrangle ABCD a square is. Determine the coordinates of C.
The Attempt at a Solution
All I have done is measure AC, CD and BC, which are 9, 9 and 12.78. But how do I get the C point from this data?
Thanks in advance
