This packet includes parts of triangles: median, altitude, perpendicular bisector, and angle bisector. Also, there are notes and examples of the centers: centroid, incenter, circumcenter, and orthocenter. There is a practice test (w/ solutions) that reviews these topics -- as well as linear equations, midpoint, and slope.. ***Note: the free preview file is EXACTLY the same as the product file. (If you would like to pay for the packet, we appreciate your support. Proceeds go to TPT, the mathplane site, and treats for my dog!). Thanks for visiting!
