  1. Calculating Angles around a Point Diving Think of three numbers that have a sum of 360°. Now think of another set of numbers, and another. Finally, working with your learning partner, can you come up with set of three numbers with a sum of 360 that no other people in the class will think of?

  2. Angles around a point There are some basic rules you need to remember when working out angles around a point … 1. All the angles around the point must total 360 degrees! 2.Opposite angles are always equal. Knowing these rules will help you solve missing angle problems. Try the ones on the next slide …
