Angles around a single point sum to 360°.
Add all angles at a point; they should total 360°.
All angles around a point add up to 360°. This principle helps solve problems involving multiple angles meeting at a point. For example, when intersecting lines form angles at a vertex, summing them to 360° allows students to calculate unknown angles. Understanding this also applies to polygons, circle sectors, bearings, and rotations. It is crucial in real-life contexts like construction, navigation, and design. Students should practice drawing multiple angles meeting at a point, adding them together, and finding missing angles to reinforce the concept. Recognizing that 360° represents a full rotation around a point is a foundation for circular geometry and working with reflex angles.
