Student will need to use trigonometry or special right triangles to find the apothem or the side length on some problems. This activity also gets students up and about. Place the 10 cards on the wall around your room. Students pick any card to begin with. They should find the area of the figure. Students then look around the room for a card that matches their answer. Then they work the next problem. They should continue until they return to the card they started with. Included are 2 versions of this activity. To help with grading, I have included student response sheets (in different formats). I like my students to draw a picture when working problems, so I have included small basic pictures of the polygons for students to glue to their answer sheet. The diagram do not include measurements to allow student to label the pictures. I also have my student highlight the important information: apothem and side length. Possible Uses Other Area Activities Area of Parallelogram using Trig and Pythagorean's Thm
How do u find the area of a regular polygon?The area of a regular polygon is one-half the product of its apothem and its perimeter. Often the formula is written like this: Area=1/2(ap), where a denotes the length of an apothem, and p denotes the perimeter.
Can a regular octagon have an area of 10 units2?36 units 18) Can a regular octagon have an area of 10 units²? Yes, it just wouldn't have integral length sides.
What is the sum of the interior angle measures?The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.
