    Eyeballing

    This little visual geometry game is a great test of your "eyeballing" skills in correcting a parallelogram, finding the midpoint of a line, bisecting angles, making a right angle, locaintg the centers of circles, etc. Kinda fun on a rainy Texas afternoon.



    Here's my result...

            My average was 8.46. Maybe I shouldn't throw away my ruler and protractor yet...

              My overall score was 3.37 I struggled with the center of the circle and the center of the triangle. I did good on the right angle, parallelogram, and angle bisection. I was decent on the line convergence.

                    Average error was 4.45.

                    Got off to a slow start, with a 14.8 on the first parallelogram (but got the last one right on the nose!)

                    Best results were the angle bisects: 0.1, 0.8, 0.7
                    My achilles heel was convergence: 10.0, 8.1, 4.2

                      My score came out at 3.9 officially but I had one really wacky score where I let go of the mouse by mistake and got a 17 so I should be <3.9

                      RAngles where my best where I consistently got less than 0.9

                              for some reason I am really good at the bisection and rightangles. I got the BS dead on twice and the RA under 0.5 a few times and never over 1.0

                              The parallelagram keeps killing me though.
