Across
- 3. two lines are perpendicular if they intersect at a right angle (90 degrees)
- 8. a line, ray, or segment that divides something (like an angle or a line segment) into two equal parts
- 9. an angle that measures exactly 90 degrees
- 10. being next to or sharing a boundary with something else
- 12. two angles are considered complementary if their measures add up to 90 degrees
- 14. a fundamental, one-dimensional object with length but no width, depth, or curvature, 180 degrees
- 15. two angles are considered supplementary if their measures sum to 180 degrees
- 17. two figures are congruent if they have the same shape and size
- 18. two non-adjacent angles formed by the intersection of two straight lines, where the angles are positioned opposite each other at the intersection point
Down
- 1. an angle that measures more than 90 degrees but less than 180 degrees
- 2. the middle point of a line segment
- 4. a fundamental concept representing a precise location in space
- 5. lines that lie in the same plane and never intersect
- 6. a portion of a line that is bounded by two distinct points, called endpoints
- 7. the point where two or more lines, rays, or line segments meet
- 11. the measure of the rotation between two lines or rays that meet at a common point, called the vertex
- 13. an angle that measures less than 90 degrees but greater than 0 degrees
- 16. a portion of a line that starts at a specific point (the endpoint) and extends infinitely in one direction
