Grade 4 geometry quiz: points, lines, line segments, and rays

📚 Quick Study Guide

📍
• Point: A point is an exact location in space. It has no size, only position. We represent it with a dot.
📏
• Line: A line is a straight path that extends infinitely in both directions. It has no endpoints. We denote it with arrows on both ends.
➖
• Line Segment: A line segment is a part of a line that has two endpoints.
☀️
• Ray: A ray is a part of a line that has one endpoint and extends infinitely in one direction.
📐
• Angles: Formed by two rays sharing a common endpoint (vertex). Measured in degrees.
↔️
• Parallel Lines: Lines in a plane that never intersect.
➕
• Perpendicular Lines: Lines that intersect at a right angle ($90^{\circ}$).
