Term 3, Week 8 September 8, 2010

This week I have learned: In maths I have learned that to find the angles in polygons you have to take two away from the number of sides, and then you have to multiply that number by 180. After that you have to subtract all the known angles and then you have found the missing angle. You can either use that method or you can find out the minimum number of triangles you can make by going from vertex to vertex without bisecting the lines that form the triangles. then you multiply it by 180 because all the angles of a triangle add up to 180 degrees because a triangle is half of a circle. After that you have to subtract all the known angles and then you have found the missing angle.
