First up, an easy one: draw a circle!

Okay, next is a classic: the perpendicular bisector.

All right, another standby: the angle bisector.

Let’s try for a fancy one now: the regular 17-gon.

Here, to change things up: a Venn diagram.

And how about a real challenge: the Cantor ternary set!

  1. Homework:

    Now that have shown how to bisect an angle. How do you trisect an angle? Work this out over the weekend and be prepared to demonstrate your techniques in class on Monday.

  2. Can’t… stop… laughing… no… air!

    Nobody warned me that compasses would be dangerous like this!

  3. Thanks for the laugh! Made my day. Wish I had this before my four day unit on compass construction. Would have made lesson planning easier :).
