any ideas?

[Georgette]

how do I figure out the distance between 2 corners of a square? For instance if I have a square that is 12 feet on each side how would I figure out the distance from the bottom corner to the top corner through the middle?

Apply the Pythagorean Theorem.

Draw a square;
draw a line inside joining your 2 corners;
what do you get?
2 identical right triangles, right?
