Constructing a Basic Angle Diagram

A simple geometric diagram shows a point O with two rays extending from it: a horizontal ray Ox and a second ray Oy angled upward to the right, forming a basic angle. Drawn in blue lines on a white background with no labels or text, the animation isolates the pure visual structure of an angle. It is useful for introducing angle notation and vocabulary to beginning geometry or trigonometry students.

Make the next one in this series

• Add an arc between Ox and Oy to mark the angle measure in degrees
• Show how rotating Oy changes the angle from acute to obtuse to reflex
• Introduce a third ray Oz to demonstrate adjacent angles summing together
