- 4. angle whose measure is 180 degrees
- 7. Set of all points
- 10. two lines are parallel if they are coplanar and do not intersect.
- 13. a logical argument in which each statement you make is supported by a statement that is accepted as true.
- 14. set of points which has infinite length but no width or height. A line is named by a lower case letteror by any two points on the line

- 6. quadrilateral with both pairs of opposite sides parallel.
- 8. is the part of a line that contains an endpoint and all points extending in the other direction.
- 9. the non-adjacent angles formed by two intersecting lines.
- 11. of a segment a point that divides the segment into two congruent segments.
