Drawing ovals and other things without maths

a better demo of how to draw an oval or as they call it – Construct an ellipse with string and pins.  Would have saved me writing this 🙂

more Geometric Constructions – or “how to draw stuff without a tape measure and protractor” ->

useful demos on those pages on making common angles like 45 degrees, 30 and 60 degrees, how to make a hexagon, how to make a line parallel to the one you’ve got.

I remember my maths teacher at school teaching us these, but I’d forgotten all about them…   right, off to find a compass and ruler to practice them.
