Maths AI-HL 3.9.1Tranformations using matrices

Tranformations using matrices – Maths IB AI – HL

🔍 Overview

This complete lesson pack introduces Geometric Transformations Using Matrices for the IB Maths: Applications & Interpretation HL syllabus. The lesson guides students through the use of matrices to perform 2D transformations, including reflections, rotations, stretches, enlargements, and translations — all using clear examples, step-by-step methods, and visual understanding.

Designed with IB pedagogy in mind, the resource builds conceptual understanding, fluency with matrix notation, and confidence applying transformations to coordinate geometry. The included examples and practice tasks align with the style and cognitive demand of official IB examination questions.
