Close enough for government work...

How good are you at "eyeballing it"? Take this test and find out!. I had to do it twice, because the first time I accidentally double-clicked my mouse and ended up with an inaccuracy rating of 38 on one of them! Ouch... Anyway, a re-test gave me this:

Your inaccuracy by category:

Parallelogram	1.4	5.4	6.1
Midpoint	3.2	5.4	0.0
Bisect angle	1.3	3.3	1.2
Triangle center	4.3	1.5	2.1
Circle center	3.6	1.0	4.2
Right angle	2.5	0.7	0.2
Convergence	1.4	2.2	3.2

Average error: 2.58 (lower is better)
Time taken: 138.2

Not the best, but I'm pretty darn proud of my 0.0 on the midpoint. I might do better if I put my desk chair back in front of my computer, my big, comfy round chair is a little low. But it's great for knitting, watching TV and playing Facebook games all at once...
