IB Math AI SL 3.1 – Introduction to 3D Geometry

This editable slide-deck comprehensively covers the key geometry and trigonometry skills required in three-dimensional space under Topic 3.1 of the IB syllabus. Students will explore how to find the distance between two points and determine their midpoint in 3-D space, calculate surface areas and volumes of various solids including right pyramids, cones, spheres and hemispheres (as well as combinations of these), and determine the size of an angle between two intersecting lines or between a line and a plane.

The resource links formulae for pyramids, and for angles, visual diagrams, and worked examples, enabling students to apply these concepts in context and interpret their geometric meaning.

With clear diagrams, step-by-step solutions and exam-style questions, this deck equips learners to handle 3-D spatial reasoning, solid modelling and angle-between-objects calculations with confidence and precision.
