IGCSE Extended Booklet 28 - Symmetry | Original 20-page PDF

My original 20-page teaching booklet, supplied as an unchanged PDF. Reflectional and rotational symmetry, solids and coordinate geometry.

The original questions, numbering, diagrams and page layout are preserved. This historical edition contains teaching notes, practice questions and selected answers. It is not a complete worked-solutions pack. Use the linked lesson description to see which questions that particular recording covers.

A separate one-page clarification PDF is included. Page 7 - Plane of symmetry: A symmetry plane gives mirror-image halves. Two equal-volume pieces alone are not enough to establish a plane of symmetry.

Lessons with Dr Taylan Çeltik connect topics through a spiral learning approach.
