Basic angle parts assessment: Vertex, sides, and naming quiz

📚 Quick Study Guide

• 📐 Angle Definition: An angle is formed by two rays (sides) sharing a common endpoint (vertex).
• 📍 Vertex: The common endpoint where the two rays of an angle meet. Think of it as the 'corner' of the angle.
• ray Sides: The two rays that form the angle.
• ✍️ Naming Angles: Angles can be named in several ways:
  • Using three points: $\angle ABC$, where $B$ is the vertex.
  • Using the vertex alone: $\angle B$ (if there's no ambiguity).
  • Using a number or letter: $\angle 1$ or $\angle x$.
• ➕ Angle Measurement: Angles are typically measured in degrees (°). A full rotation is 360°.
