Across
- 1. A straight path through two points that continues without end in both directions
- 2. Lines that meet at the point of intersection
- 4. A part of a line that begins at one point and extends without end in one direction
- 7. An angle that measures exactly 180 degrees
- 10. These lines intersect to form right angles
- 12. Lines that never intersect and are in different planes
- 13. An angle that is less than 90 degrees
- 14. The branch of mathematics that identifies and studies points, lines, angles, plane figures, and 3D figures
- 15. The point where the lines meet to form an angle
Down
- 1. A part of a line between two endpoints
- 3. The tool used to measure an angle
- 5. Having the exact same shape and size
- 6. a 2D flat surface that extends in all directions without end
- 8. These lines never intersect but are in the same plane
- 9. An angle that is greater than 180 degrees but less than 360 degrees
- 11. An angle that is more than 90 degrees but less than 180 degrees
