 Circumcenter
You will need to know your conjectures
and your definitions –in particular the
new: centroid, orthocenter, incenter,
circumcenter, concurrent lines,
circumscribed circle, inscribed circle,
perpendicular bisector, median, altitude,
angle bisector
Be able to find unknown parts of the
medians of a triangle.
Be able to describe how the circumcenter
or incenter conjectures follows from the
perpendicular bisector or angle bisector
conjecture. Test will include: True/False,
Fill in the blank-short answer,
constructions, reasoning (explain why)
