Understanding Angles - Presentation
In this presentation, students are given a brief refresher on angles before being shown how they can use maths to find the size of missing angles without measurement.
This presentation is part of a comprehensive unit on angles for Year 6 teachers to engage students in understanding the relationships between angles on a straight line, angles at a point, and vertically opposite angles.
