This a STUDENT VERSION of a PowerPoint lesson explaning Geometric Mean using an Altitude Method and a Leg Method. Most people separate the large triangle into 3 separate triangles. This method doesn't separate the triangles at all. I find this to be much easier to teach and much easier for the students to learn. I have them use different colors in their notes, just as I do in the PowerPoint.
Purchase the teacher version to print and go along with the student version!
