Area of regular polygons
Learn how to find the area of regular polygons with me using the apothem and trigonometry. This is a 25 minute video because it has 4 examples of me working out the problems followed a problem for you to try on your own that is similar to each example.The prerequisite skills are understanding the polygon angle sum theorem and finding the side length of a right triangle using trigonometric functions (sine, cosine and tangent). The videos for these skills are linked below.
