Across
- 3. where an image moves
- 6. a shape with all equal sides and angles
- 9. all sides the same
- 13. series of shapes forming a sort of tiling
- 16. is like a translation but on the coordinate system
- 17. you can draw lines in a shape and it’s always the same on both sides
- 18. flips over its own axis
- 19. one right angle and two acute ones
- 20. how something is represented in appearance
- 21. the point that something is rotated on
Down
- 1. a y and x axis with positive and negative coordinates
- 2. 3 angles less than 90°
- 4. two sides of equal length
- 5. where two shapes are the same but different sizes or angles
- 7. 3 unequal sides
- 8. when an image pivots into another position
- 10. one quarter of the coordinate system
- 11. how an images position appears
- 12. one interior angle over 90°
- 14. any movement in a shape
- 15. it always looks them same when you rotate it
