The idea of median may be explained to the child using paper folding. As the child
himself is facilitated to perform the activity in finding the medians of a triangle,
he/she may understand the idea effectively.
- Centroid
The point of concurrence of the medians of a triangle is called the centroid of the
triangle. Note that the centroid of a triangle divides the medians in the ratio 2:1.
Centroid of a triangle is normally denoted by the letter G.
The concept of centroid may be taught to the child through the paper folding. The
procedure to be followed is mentioned in the creative mathematics section.
- Altitude
An Altitude of a triangle is a perpendicular line segment from a vertex of the triangle
to the opposite side.
The idea may be taught with the assistance of paper folding.
- Orthocenter
The point of concurrence of the altitudes of a triangle is called the orthocenter and is
normally denoted by the letter ‘O’.
