📚 Quick Study Guide

  • 📐 An angle is formed by two rays sharing a common endpoint called the vertex.
  • 📏 Angles are measured in degrees (°).
  • острый A acute angle is less than 90°.
  • 🛄 A right angle is exactly 90°.
  • ↔️ An obtuse angle is greater than 90° but less than 180°.
  • ➡️ A straight angle is exactly 180°.
  • 🔄 A reflex angle is greater than 180° but less than 360°.
  • 💡 To estimate angles, compare them to known angles like 45°, 90°, and 180°.
