Congruence Revision and Proofs | 18 Worked Examples | Edexcel GCSE Higher Maths
18 exam-style Edexcel GCSE Higher (1MA1) congruence questions with full worked solutions and B1/M1/C1 mark schemes. Every diagram is drawn accurately to match its labels.
What’s inside:
Easy: spotting congruent shapes and triangles, naming SSS, SAS, ASA/AAS and RHS, and why AAA and SSA are not enough.
Medium: missing sides and angles in congruent shapes, congruence from transformations, and a scaffolded first proof.
Hard: unscaffolded formal proofs (parallelograms, isosceles triangles, squares, kites, midpoints, alternate angles, RHS) and grade 7 to 9 questions combining congruence with angle facts and trigonometry.
Includes a How to write a congruence proof box and model proofs with the reason for every step. Typeset in LaTeX, print-friendly.
Ideal for: students sitting Edexcel GCSE Higher Mathematics (1MA1), plus tutors and teachers building targeted practice.
