1. Coordinates-things to make you go hmmmm….

2. The points (3, 4) and (4, 3) are both the same distance from (0, 0).

3. If you start at (3, -7) and move up 4, then you will end up at (3, -11).

4. The points (3, 4), (5, 4), (3, 7) and (5, 7) make a square.

5. The points (3, 4), (4, 7), (7, 6) and (6, 3) make a square.

6. The distance between (1, 5) and (10, 7) is 11 squares.

7. If you use the x axis as a mirror line, then the point (3, 10) will get reflected to (3, -10).

8. If you use the line shown as a mirror line, then the point (3, 10) will get reflected to (3, -10). 2

9. If you start at (3, 0) and move vertically up or down, the x coordinate will always be 3.

10. If you start at the point (2, 2) and move 2 squares to the right and 2 squares down, you will be at (4, 4).

11. If you are not on one of the grid lines it is impossible to give the coordinates of where you are.

12. To tell someone where you are in 3-dimensions you need an x and y axis and also a z axis. z y x

13. The half way point between (1, 1) and (3, 6) is (2, 3).
