Test Questions on Lines, Line Segments, and Rays for 5th Grade Math

📚 Quick Study Guide

• 📏 A line extends infinitely in both directions. We represent it with arrows on both ends: $\overleftrightarrow{AB}$.
• ✂️ A line segment is a part of a line with two endpoints. We denote it as $\overline{AB}$.
• ☀️ A ray has one endpoint and extends infinitely in one direction. We write it as $\overrightarrow{AB}$, where A is the endpoint.
• 📐 Collinear points are points that lie on the same line.
• ✨ Remember the order of letters matters when naming a ray! $\overrightarrow{AB}$ is different from $\overrightarrow{BA}$.
