Angles

Explore Euclid’s Definitions 8–12 and discover how angles arise from the relationship between meeting lines, shaping geometry, force, movement and mechanics. A line on its own gives direction. But when two lines meet in a plane, direction is no longer considered alone. One line now stands in relation to another. Their meeting creates an inclination: an opening between the two lines that can be recognised, compared and named. This relationship was not present in either line by itself. It arises through their meeting.
