GCSE Secondary Maths Age 13-17 - Geometry & Measures: Construction - Explained

The video tutorial explains how to construct the perpendicular bisector of a line segment using a ruler and compasses. It emphasizes the importance of showing all construction lines to avoid losing marks. The tutorial provides step-by-step instructions on using a compass to draw arcs and a ruler to connect intersection points, forming the bisector. It also discusses scoring criteria and alternative methods if a compass is unavailable.
