- 14. is a transformation that moves points the same distance and in the same direction.
Down

- 2. Is a closed plane figure with at least three sides
- 3. is a ray that divides an angle into two congruent angles
- 5. segment or rays intersect to form right angles.
- 7. has all sides congruent and all angles congruent.
- 9. is when the sum of the measures of two angles is 180 degrees
