Answer 1

If you connect the opposite corners, you get a diagonal of a right triangle.  The two sides of the windowpane make up the legs of the right triangle.

 

Use the Pythagorean theorem to find the diagonal.

 

Distance between opposite corners = √((length of windowpane)² + (width of windowpane)²)
