This week we have been learning about how to measure interior angle sums, interior angles and exterior angles of any shape. This was quite new, though it was ok since we knew what the shapes were.
To measure the interior angle sum, you take the number of sides of a shape minus 2, then times that by 180. Next, we find the interior angle. Take the interior angle sum divided by the number of sides. Finally the exterior angle. The equation to find this is 180 - interior angle.
In simpler words,
{ NUMBER OF SIDES - 2 } x 180 = INTERIOR ANGLE SUM
{ INTERIOR ANGLE SUM } ÷ { NUMBER OF SIDES} = INTERIOR ANGLE
180 - { INTERIOR ANGLE } = EXTERIOR ANGLE
