This geometry video tutorial explains how to identify the location of the incenter, circumcenter, orthocenter and centroid of a triangle. The incenter can be found be drawing the 3 angle bisectors of a triangle and identifying the point of intersection. The incenter always lie inside of a triangle. The incenter is the center of the circle that is inscribed in a triangle. The location of the centroid of a triangle can be identified by the intersection of the three medians. The orthocenter of a triangle can be located by finding the intersection of the three altitudes of a triangle. For an acute triangle, the orthocenter lies inside of the triangle. For a right triangle, it lies on the right triangle. For an obtuse triangle, the orthocenter lies outside of the triangle. The circumcenter of a triangle can be found by the intersection of the three perpendicular bisectors. The circumcenter is the center of the circle that is circumscribed about the triangle. • Circles - Area, Circumference, Radius: • • Circles - Area, Circumference, Radius... • Circles - Chords, Radius, Diameter: • • Circles - Chords, Radius Diameter -... • Lines, Rays, Line Segments, Angles: • • Lines, Rays, Line Segments, Points, A... • 2 Column Proofs - Cong.
