📐 Angles & Constructions
This quiz tests your understanding of angle measurement and classification in the context of Ontario Grade 6 Mathematics. You'll explore how angles are measured in degrees, learn to identify and classify different types of angles, and discover how to construct precise angles using compasses and straightedges. These foundational skills are essential for geometry and spatial reasoning. **What you'll learn:** - How to measure and classify angles (acute, right, obtuse, straight, reflex) - The relationship between angles and degrees - How to construct angles of 60°, 90°, and 120° with tools - How to solve problems involving angle relationships and sums
