In this video, one thing that I really like is that Ms. Castaneda uses a program where she can show the relationship of the values even when the triangle changes in size. I also really like that this video is primarily focused on the diagram of the triangle rather than on words. It is very intuitive and engaging.

Ms. Castaneda does a great job explaining the concept of an incenter and explaining all the terms that go along with that definition (angle bisectors, etc). She thoroughly explains the definition of an incenter showing both the angle bisector aspect as well as the equidistant aspect.  I like the review at the end. Ms. Castaneda is very articulate in her explanation making it easy to follow.
