Provide the definition for the following:
Circumcenter
Centroid
Inscribed Circle
Circumcenter - the point of which is equidistant from all the vertices of your triangle
Centroid - Point of intersection of the medians of a triangle
Inscribed Circle - circle contained in the triangle; it touches (is tangent to) the three sides.

Provide the definition of the following:
Hinge Theorem
Triangle Midsegment Theorem
CPCTC Theorem
Hinge Theorem - if two sides of two triangles are congruent and the included angle is different, then the angle that is larger is opposite the longer side.
Triangle Midsegment Theorem - The segment joining the midpoints of two sides of a triangle is parallel to and half the length of the third side
CPCTC Theorem - corresponding parts of congruent triangles are congruent.
