Supplementary Angles

[b]Keywords and Ideas: Straight Line = 180° | Supplementary Angles | Angles around a point | Angles are measured Clockwise [/b] Drag point E passed 180° to see angles around a point Drag point C to get further supplementary angles Drag point A or B to re-angle the straight line

[b]The angle EDA only appears when angle EDC is greater than 180[/b]
