Lesson 7 - Triangle Centers Despite the trend set in this Unit, the last lesson did not wrap up, or continue anything. In fact, it introduced a new concept known as Triangle Centers. In this lesson, I learned that in a triangle, there are many different line segments you can create using midpoints, angles, and the whole triangle in general. But the thing this lesson mainly focused on was the intersection point between these segments, which were called the circumcenter, the centroid, the orthocenter, and the incenter. Also, many properties about these segments and points of concurrency were given to us as well, which we can possibly use as reasons in our proofs, or maybe just to solve problems instead.
