Can you think of a statement, not necessarily in geometry, which sounds true, appears to be true in some cases, but is actually false.
Yes, they only appear to have the same gradient (as matt said). Try drawing the same problem, with great accuracy, on a piece of paper.recon said:It puzzles me. I don't see how a triangle 2 units high and 5 units wide can have the same gradient as a triangle 3 units high and 8 units wide. Did they cheat?
