(1) As shown in Figure 2, play the "treasure hunt" game. If the treasure is hidden under the letter plate (3, 3), then it should be found under the letter ______.

(2) As shown in Figure 3, if the position of point A is (2, 1), then the position of point B is ______, the position of point C is ______, and the positions of point D and point E are _____________ respectively.

(3) As shown in Figure 4, if the position of point A is (1, 2), then the position of point B is ____, and the position of point C is ____.

Exercise: P40, as shown in the figure, land A represents the intersection of 2nd Street and Lane 5, land B represents the intersection of 5th Street and Lane 2, if (2,5) is used to represent the location of Land A, then “(2,5 )→(3,5) →(4,5) →(5,5) →(5,4) →(5,3) →(5,2)” represents a route from point A to point B, Please use ordered number pairs to write another route from point A to point B.

Do it

"Monster Pac-Man" is a computer game. The ● mark in the picture indicates the locations that the "monster" has passed successively. If (1,2) is used to indicate the second location that the "monster" has passed, then you can use In the same way, can you express several other locations that the "monster" passes through in the picture?

Job design

1. Design a graph that is easy to describe using pairs of ordered numbers, and then tell your classmates about these pairs of ordered numbers to see if others can draw your graph.

2. Based on the actual situation of our school, please use appropriate ordered number pairs to express and describe the positional relationship of each class.
