Angles and Polygons | Edexcel GCSE Foundation | 40 Worked Examples

40 progressive Edexcel GCSE Foundation (1MA1) angles and polygons questions with full mark-scheme style worked solutions. Every line is explained and every mark is annotated at the exact point it would be awarded, using Edexcel’s own B, M, A, P and C mark codes, including the written angle reasons the examiner wants word for word.

What’s inside:
Easy: angles on a straight line, angles at a point, vertically opposite angles, angles in a triangle and quadrilateral, isosceles and right-angled triangles, the exterior angle of a triangle, and the interior and exterior angles of regular polygons.
Standard: alternate, corresponding and co-interior (allied) angles on parallel lines with reasons, finding the number of sides from an interior or exterior angle, angle problems set up as equations, and multi-step angle chases.
Challenging: regular polygons meeting at a point, a regular hexagon and pentagon sharing a side, parallel-line problems solved with a helper line, isosceles angle reasoning, and ‘show that two lines are parallel’ proofs.

A clear diagram accompanies every geometry question. Each solution breaks the work down one step at a time, in plain English with no jargon, so Foundation students can follow the reasoning and reproduce the method under exam pressure. Typeset in LaTeX for clean, print-ready notation.

Ideal for: Year 10 and 11 students sitting Edexcel GCSE Foundation Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
