Today's maths follows on from yesterday but looks at a different method for finding interior angles. In today's lesson, you will find that polygons can also be divided into triangles in order to work out what the angles amount to.


Please watch the video that I upload before completing activity two. The PowerPoint will help you with activity one.


When completing activity 2, if you wish to use yesterday's method, (n-2) x180, that is absolutely fine. Choose whichever method suits you the best.
