Angles

This is a great little task which can be created in 1 minute flat! With just a couple of folds, we have an exploratory exercise into basic angle facts.

1. Fold down the centre lengthways then unfold.

2. Bring the short side up and to the left bisecting the bottom left right angle then unfold.

3. Bring the short side up and to the right with the bottom left vertex matched up to the centre line. Keep this fold.

4. Take the previous fold and match the folded edge up to the right side then unfold. You will have trisected the bottom right angle.
