Bisectors of Triangles As you well know by now, being able to deduce key information from a limited set of facts is the basis of geometry. An important type of segment, ray, or line that can help us prove congruence is called an angle bisector. Understanding what angle bisectors are and how they affect triangle relationships is crucial as we continue our study of geometry. Let's investigate... read more

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
