Class Work: Where will they meet?

This activity involves construction of triangles (given specific properties) and application of perpendicular bisectors.

Geometrical Construction: Perpendicular Bisector

 This is a task carried out during lesson. 

Post a photo of your work as an evidence that you could construct the pair of perpendicular bisectors. Remember that the pencil marks (especially the arcs) are clear.
