Geometry Quiz Review 6.2-6.3 Perpendicular Definition Point Of Concurrency Angle Bisector Bisector Is perpendicular Bisects to a segment at angles its midpoint (bisects segments) Circumcenter Property = distance to vertex Incenter Median Segment from vertex to midpoint of sides Altitude Segment from vertex perpendicular to side or line containing side Centroid Orthocenter Centroid = distance is 2/3 of from sides distance from vertex to side None Circumcenter Theorem equidistant Incenter Theorem equidistant USING MEDIANS OF A TRIANGLE THEOREM 6.7 Centroid Theorem The centroid of a triangle is two-thirds of the distance from each vertex to the midpoint of the opposite side. If P is the centroid of ABC, then 2 AP = AD 3 BP = 2 BF 3 CP = 2 CE 3 P
