1 Medians and CentroidA median of a triangle is a line segment that is drawn from the _________ to the ___________ of the opposite side.A centroid is the point where all ______ of the ________ intersect.
2 Angle Bisector and Incenter An angle bisector in a triangle is drawn from the ________ to the opposite side (not necessarily the middle) so that the _______ is cut in _______.The incenter is the point where all _____ of the _________________ intersect.
3 Perpendicular Bisector and Circumcenter A perpendicular bisector of a triangle is a segment drawn from the _________ of the side and is ______________ to that side.A circumcenter – is the point where all 3 _________________ ____________
4 Label each segment as a median, angle bisector, or perpendicular bisector.
5 ClassworkConstruct the centroid, circumcenter, and incenter for each triangle.Use centimeters when measuring and LABELING the side lengthsLABEL how many degrees each angle of the triangle is.
