The Centroid Of A Triangle - By Cathal Golden
The Centroid Of A Triangle Is The Intersection Of Any 2 Of The Medians Of The Triangle. A Median Is A Line From The Mid-point Of One Of The Lines Of The Triangle To The Opposing Vertex(eg In A Triangle Abc, The Mid-point Of Bc Is Joined To A) The Centroid Is The Centre Of Gravity Of The Triangle [View Applet]

Parametric Equation Of A Line - By Marianne Herbert
