The Eyeballing Game
Library Home || Full Table of Contents || Suggest a Link || Library Help
|Test your ability to "eye up" geometric figures with this timed Flash challenge. First consult the help documentation to correctly calibrate your monitor resolution and aspect ratio; then click and drag the blue ray or point to accurately construct the indicated parallelogram, segment midpoint, angle bisector, triangle center, circle center, right angle, or convergence of three intersecting rays. Wandel, a woodworker, developed the eyeballing game because he suspected great variation in peoples' ''ability to notice that things might be just a little off square, off centre, or not quite straight."|
