Orthocenters by: Aubrey
An orthocenter is the common intersection of the three altitudes of a triangle or their extensions (according to Webster.com).



Basic Orthocenter

To construct the Orthocenter place curser on the page and left click mouse to create first point. Drag the line to create the second point and left click mouse. You have now constructed a line. Move curser up/down/left/right to create the third vertex of the triangle. You will see a free floating point either within or outside the triangle, this is the Orthocenter. Congratulations on your construction!
