Across
- 6. A change in the position, size, or shape of a figure.
- 7. of rotation The number of times a figure can be rotated to match itself during a full 360-degree turn.
- 14. A transformation that slides every point of a figure the same distance and in the same direction.
- 15. of rotation The fixed point around which a figure is rotated.
- 16. A statement that has been proven to be true based on previously established statements, such as axioms and other theorems.
- 17. The process of applying a transformation to a figure to produce a new figure.
- 19. A transformation that flips a figure over a line, called the line of reflection.
- 24. of symmetry A line that divides a figure into two identical parts that are mirror images of each other.
- 25. lines Two lines that intersect to form a 90-degree angle.
- 27. definition A precise and exact description of a term.
- 28. A quantity that has both magnitude (size) and direction. It is often used to describe a translation.
- 30. reciprocal Two numbers whose product is -1. The slopes of perpendicular lines are negative reciprocals of each other.
- 31. polygon A polygon that is both equilateral (all sides equal) and equiangular (all angles equal).
- 32. A measure of the steepness of a line, calculated as the change in y-coordinates over the change in x-coordinates.
- 34. symmetry A figure has rotational symmetry if it can be rotated by a specific angle (less than 360°) about a center point and look the same.
- 35. The point where two or more lines cross each other.
Down
- 1. The points where two or more lines or segments meet to form a corner.
- 2. of reflection The line over which a figure is reflected.
- 3. A set of values that shows an exact position on a coordinate plane.
- 4. of rotation The amount of turn, measured in degrees, around the center of rotation.
- 5. The specific characteristics of a geometric figure.
- 8. An exact location in space with no size or shape.
- 9. The new figure created after a transformation.
- 10. A polygon with four sides and four vertices.
- 11. To provide a reason or explanation for a statement.
- 12. Figures that have the same size and shape.
- 13. A property of a figure that remains unchanged under a transformation.
- 18. The original figure before a transformation.
- 20. The figure produced after a symmetry transformation.
- 21. A term describing a figure with all angles of equal measure.
- 22. A term describing a figure with all sides of equal length.
- 23. A logical argument that demonstrates the truth of a statement.
- 26. A transformation that turns a figure about a fixed point, called the center of rotation.
- 29. transformations A transformation that preserves the size and shape of a figure.
- 33. angle An angle inside a polygon formed by two adjacent sides.
