This animation shows two rays sharing a common endpoint O: one horizontal ray and one angled upward to the right, drawn in blue on a white background. It visually introduces the basic components of an angle—the vertex and the two rays—laying the groundwork for understanding how angles are measured and classified. Useful for students beginning geometry who need a clear, simple picture of what an angle actually is.
