Unit One-Vocabulary
Across
- 2. A transformation that turns a figure about a fixed point through a given angle and a given direction.
- 5. The ratio of any two corresponding lengths of the sides of two similar figures.
- 7. A transformation that "slides" each point of a figure the same distance in the same direction.
- 13. These angles are on opposite sides of the transversal and are outside the other two lines.
- 14. The mapping, or movement, of all the points of a figure in a plane according to a common operation.
- 15. These angles are on the same side of the transversal and are outside the other two lines.
- 16. A line that crosses two or more lines.
- 17. Angles that have the same relative positions in geometric figures.
Down
- 1. Figures that have the same size and shape.
- 3. A transformation that "flips" a figure over a line of reflection.
- 4. Figures that have the same shape but not necessarily the same size.
- 6. The amount of rotation about a fixed point.
- 8. These angles are on opposite sides of the transversal and are in between the other two lines.
- 9. These angles are on the same side of the transversal and are between the other two lines.
- 10. Adjacent, supplementary angles. Excluding their common side, a linear pair forms a straight line.
- 11. A line that is the perpendicular bisector of the segment with endpoints at a pre-image point and the image of that point after a reflection.
- 12. A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distances from the center by a common scale factor.
