Across
- 3. Two lines that intersect to form a 90° angle
- 6. A transformation across a line, called the line of reflection
- 8. Is formed by two or more different regular polygons, with the same number of each polygon occurring in the same order at every vertex
- 14. A change in position, size or shape of a figure
- 15. Divides the figure into two congruent halves
- 18. A transformation that turns a figure around a fixed point, called the center of rotation
- 19. A transformation that changes the size of a figure but not the shape or direction
- 20. Two lines that do not intersect and are not parallel
Down
- 1. A transformation where all the points of a figure are moved the same distance in the same direction
- 2. When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles
- 4. Two lines in the same plane that, no matter how far they extend, do not intersect with each other
- 5. If it can be reflected across a line so that the image coincides with the preimage
- 7. Two Angles that add up to 90 degrees
- 8. Interior angles may be defined as two interior angles lying on the same side of the transversal cutting across two parallel lines
- 9. A transformation that does not change the shape or size of a figure
- 10. Is formed by congruent regular polygons
- 11. Angles that are formed on opposite sides of the transversal but outside the two lines
- 12. Two angles that add up to 180 degrees
- 13. Angles that are formed on opposite sides of the transversal and inside the two lines
- 16. A repeating pattern that completely covers a plane with no gaps or overlaps
- 17. Two parallel lines intersected by a third line at an angle
