Yipes... embarrassing...

Details please. Don't tease me.

By the graph that's below average.
Strange because I have a pretty good eye for level and plumb.

2nd try 81.91 seconds, score 5.13

I realized right now I played without my glasses... I will try again!

These tired old eyes still remember some of my old engineering skills.



Test me again in a couple of weeks.

Third try was 4.36 in 106.15 and the first two were 5.something in 120+ seconds. I had to close the window or I'd still be playing at 11:30 tonight and have a really worn out forefinger.

Total time: 122.75

Your inaccuracy by category:

Parallelogram 50.1 35.3 44.6
Midpoint s 8.6 11.1 14.5
Bisect angle 14.3 5.7 1.5
Triangle center 38.5 0.9 25.7
Circle center 0.5 1.6 5.5
Right angle 0.2 0.6 1.0
Convergence 82.9 27.1 68.2

Average error: 20.88 (lower is better)
Time taken: 154.5

Off to try again, this time as quickly as possible... this is so much fun and probably good for the brain/eyes.

First try, ladies and gentlemen.

Sweet.

... not so good. I struggle a lot with these trifocals. I used to be good at this sort of thing.

I was great at bisecting the angle, finding the point of convergence, and finding the center of the circle.

I totally sucked at finding the triangles' centers, though.


Fun stuff!

The first two times I misunderstood the question! Darn!
