Grade 4 • Mathematics • Geometry
Geometry Vocabulary
- Point: an exact position or location
- Angles: the figure formed when two rays or line segments share the same endpoint
- Line: a straight path extending in both directions with no endpoints
- Perpendicular Lines: lines that intersect to form right angles
- Line Segments: a part of a line that includes two points, called endpoints, and all the points between them
- Parallel Lines: lines in a plane that never intersect
- Ray: a part of a line, with one endpoint, that continues without end in one direction
- Two-Dimensional Figure: a closed plane figure with length and width
- Symmetry: when one half of a figure looks like the mirror image of the other half
