Objectives
Introduce perpendicular bisectors in a triangle
Estimated Time
30 minutes.
Prerequisites/Instructions, prior preparations, if any
Ensure that circles, triangles, perpendicular bisectors and their constructions are covered
Materials/ Resources needed
Digital resources: Laptop, geogebra file, projector and a pointer.
Geogebra files: This eogebra file was done by ITfC-Edu-Team.
Process (How to do the activity)
