geometry

2. segment: part of a line consisting of two end points and all points between them
5. of an angle: one of the two rays that form an angle
6. bisector: a ray that divides an angle into two congruent angles
7. bisector: a line, ray, or segment that divides a segment into two congruent segments
9. the figure being transformed
11. of an angle: the common endpoint of two rays that form an angle
16. angles: two angles whose measures have a sum of 180
18. the creation of a geometric figure using tools such as a ruler, straightedge, compass, or protractor
20. angles: the nonadjacent angles formed by two intersecting lines
22. points that lie on the same plane
23. An undefined term that names a location
25. the point that divides the segment into two congruent segments

1. points that lie on the same line
3. An undefined term that is a straight path with no thickness and extends forever in all directions
4. a unit of angle measure; 1 degree is 1/360 of a circle
8. Lines or planes that do not intersect
9. an undefined term that is a flat surface with no surface with no thickness that extends forever in all diretions
10. a line that intersects two coplanar lines at two different points
12. lines: lines that intersect at 90 angles
13. a transformation that shifts or slides every point of a figure or graph the same distance in the same direction
14. a point at the end of a segment or the starting point of a ray
15. a part of a line that starts at an endpoint and extends forever in one direction
17. angles: two angles whose measures have a sum of 90
19. angles: congruent angles which are on the same side of the transversal
21. formed by two rays that share a common endpoint
24. new figure formed by the transformation
