and finally we use pythagoras theorem (pythagoras formula to find that diagonal line)

Shall we try now; distance between A(1,1) (x1,y1) and B(7,-7) (x2,y2)

So it would be 6^2+-8^2 which is -28. And it would be the square root of -28?

6^2= 36 (-8)^2= 64

make sure you use brackets if you are using your calculator :) now add them both up and dont forget to take the square root!

36+64=100 and the square root of 100 is 10. So the third side would be 10.
