Across
- 1. A distance-preserving transformation between metric spaces.
- 5. Any way of moving the points on a plane so that the relative distance of the points stay the same and that the relative position of the points stay the same.
- 7. Two or more lines that do not intersect but are not parallel.
- 8. The sum of two angles that equal 90 degrees.
- 10. An angle that measures less than 90 degrees.
- 11. Shows an exact location.
- 12. Part of a line that has two endpoints.
- 14. An angle whose sides lie in opposite directions from the vertex, equals two right angles.
- 16. Straight lines that do not intersect at any point.
Down
- 2. An angle of 90 degrees.
- 3. An angle that measures greater than 90 degrees.
- 4. Measurements that add up to be 180 degrees.
- 6. When two or more lines intersect, share a common point.
- 9. A part of a line that has a fixed starting point but no endpoint.
- 13. Lines that intersect at right (90 degrees) angles.
- 15. A line that crosses at least two other lines.
