Medians and centroid of a triangle

Objectives
To introduce medians of a triangle

Estimated Time
30 minutes

Prerequisites/Instructions, prior preparations, if any
Types of triangles, their medians and their constructions should have been covered.

Materials/ Resources needed
This geogebra file has been done by ITfC- Edu- Team

Process (How to do the activity)

 * 1) The teacher can use this geogebra file to show how the position of centriod is constant in different triangles.
 * Developmental Questions:
 * 1) Which type of triangle is this ?
 * 2) What is a median ?
 * 3) How do you identify the midpoint of the side ?
 * 4) Which is the point of concurrency of medians of the triangle ?
 * 5) Identify the position in different triangles.
 * Evaluation:
 * 1) What is the position of centriod in different triangles ?
 * Question Corner:
 * 1) Why do you think the centriod always remains in the centre for every type of triangle ?
 * 2) What does the centriod indicate ?
 * 3) What are the practical applications of the centriod ?
