Centroid, Orthocenter, Incenter, Circumcenter, Euler Line & Nine-Point Circle

2018-01-18 08:27
This applet demonstrates the geometric constructions of a triangle's centroid, orthocenter, incenter, and circumcenter, along with the Euler line and nine-point circle. Using basic commands like segments, midpoints, perpendicular lines, angle bisectors, and circles, it visually presents the relationships among these classical elements, making it ideal for plane geometry study.
