IGCSE Extended Booklet 24 - Angles and Polygons | Original 34-page PDF

My original 34-page teaching booklet, supplied as an unchanged PDF. Angle facts, parallel lines, polygons, three-dimensional shapes and surface area.

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 4 - Acute angles: An acute angle is strictly greater than 0° and strictly less than 90°. The printed table incorrectly includes the zero-angle endpoint. Page 33 - Question 25(c): Keep AB = √65 cm until the final surface-area calculation. The total is 2 × ½ × 4 × 7 + 6(4 + 7 + √65) = 142.373546… cm², or 142.37 cm². The printed 142.36 uses a prematurely rounded hypotenuse. This later question is outside the associated recording, which covers selected material on the first 22 pages.
