Can someone please help wright a proof for the following.
given: JKLM is a square
prove: MK is perpendicular to LJ
the figure in front of me is a square labeled JKLM and there are diagonals JL and KM
1 answer
aren't the corners 90 degrees, bisected by the diagonols? And then in any triangle, the sum of angles 180? So that makes the central angles 90, or perpendicular.
