Interior Angles of Polygons
- Draw a range of different polygons. You can use the Segment tool or Polygon tool to draw irregular polygons (where the sides are not the same length) or the Regular Polygon tool to draw regular polygons.
- Use the Angle tool to measure the interior angles of your polygons.
- Add these angles together to make sure that the total is the same as that given by sum of interior angles of a polygon = (number of sides - 2) x 180o.
