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