Real-World Examples of Rays, Segments, and Angles in Everyday Life

📚 Quick Study Guide

• 📏 Line Segment: A part of a line that is bounded by two distinct end points and contains every point on the line between its endpoints.
• ☀️ Ray: A part of a line that has one endpoint and extends infinitely in one direction. Think of it like a sun ray!
• 📐 Angle: Formed by two rays sharing a common endpoint, called the vertex. Angles are typically measured in degrees (°).
• ➕ Acute Angle: An angle measuring between $0°$ and $90°$.
• 🧮 Right Angle: An angle measuring exactly $90°$.
• ➖ Obtuse Angle: An angle measuring between $90°$ and $180°$.
• ➗ Straight Angle: An angle measuring exactly $180°$.
