Geometry-Semester 1

4. A location
6. Identical in form
8. Adds up to 180 degrees
11. Angles made by two intersecting lines
14. A ray that has its endpoint at the vertex of the angle and that divides the angle into two congruent angles
15. An isometry in which every point and its image are on opposite sides and the same distance from a fixed line
17. A flat infinite surface
19. Matching or in the same position
20. The ratio of corresponding lenghts in similar figures
22. An isometry in which each point is moved by the same translation vector

1. Identical in shape but not necessarily in size
2. A point of intersection of two or more rays or line segments in a geometric figure
3. An isometry in which each point is moved by the same angle measure in the same direction along a circular path about a fixed point
5. Adds up to 90 degrees
7. A line extending from a point
9. A nongrid transformation that enlarges or reduces a geometric figure by a scale factor relative to a point
10. Two non-overlapping angles with a common vertex and one common side
12. By the degrees
13. The point that bisects the segment
16. Two non collinear rays having a common endpoint
18. A linear pair of angles that is formed when two lines intersect
21. An ongoing connection
23. The result of moving all points of a figure according to a transformation
