Areas of Polygons and Circles

Areas of Polygons and Circles Let's move away from the widely-dreaded two-column proofs that we have been doing in the previous sections, and focus on geometry that revolves solely around computations. In this section, we will use our knowledge of different polygons and circles to help us measure their areas. In the two-dimensional plane, we use area to express a defined quantity... read more


Areas of Circles and Sectors

Areas of Circles and Sectors In order to work on the final section of our study of areas, we must first learn about a shape that we have not discussed at all in the past. In fact, this shape is not a polygon at all, which means that it doesn't have vertices or sides. The shape we are going to focus on in this section is called a circle. Let's begin this lesson by examining the... read more
