Points of Concurrency Triangles
three or more Point of Concurrency- ____ lines (rays or segments) that intersect are concurrent called _______. The point where they point meet is called the “_______of concurrency” Concurrent lines Lines that are not concurrent
Circumcenter made from perpendicular bisectors Circumcenter– all three perpendicular bisectors of a triangle intersect to form a point called a circumcenter. Fact Equidistant from all three vertices
Incenter made from Angle Bisectors Incenter – all three angle bisectors of a triangle intersect to form a point called the incenter. Fact Equidistant to the sides Distance to sides is vertical
Centroid made from medians Centroid – all three medians of a triangle intersect to form a point called the centroid. Fact Vertex to Centroid: 2/3 total median Centroid to Midpoint: 1/3 total median
Orthocenter made from altitudes Orthocenter– all three altitudes of a triangle intersect to form a point called an orthocenter. Fact Orthocenter can be inside, outside, or on the right angle.
