19. amount of space that something takes up
20. lines in the same plane which intersects to form a right angle.
21. lines that meet or cross

1. an angle measuring between 90 and 180 degrees
4. lines in the same plane which intersects to form a right angle.
6. a polygon with three sides

15. the turn or bend between two intersecting lines, line segments, rays, or planes
17. a portion of a line extending in one direction from a point
18. Lines that lie in the same plane and never meet.
