1Medians 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.
2Angle 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.
3Perpendicular 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 _________________ ____________
4Label each segment as a median, angle bisector, or perpendicular bisector.
5ClassworkConstruct 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.
