angles at a point

Encourage learners to try different values for the angles. The rule 'pops' out most easily when the angles are multiples of ten. Be aware that the angles displayed are rounded to the nearest degree, so it's possible that the total may be 359, 360 or 361 degrees. (It is to minimise this that I chose to position the three points on the circumference of the same circle - this seems to help a bit.)
