Part One Content: Basic Knowledge Key Points

Knowledge point 1: Row and column positioning method

1. During recess, the positions of Xiao Ming, Xiao Li, and Xiao Liang are as shown in the figure. If Xiao Ming’s position is represented by (0,0) and Xiaoli’s position is represented by (2,1), then Xiao Liang’s position It can be expressed as (C)

A.(5,4) B.(4,5)

C.(3,4) D.(4,3)

2. As shown in the figure, Xiaohua starts from point O, first walks 40 m to the west, and then walks 30 m to the south to reach point M. If the position of point M is represented by (-40,-30), then (10,20) The position represented is (B)

A. Point A B. Point B

C.Point C D.Point D

3. On the movie ticket, if "No. 4 in row 8" is recorded as (4,8), then (1,5) means "No. 1 in row 5".

Knowledge point 2: Azimuth + distance positioning method

4. Xiao Ming took a cruise ship to go out to sea. The results of the radar scanning detection on the cruise ship are as shown in the figure. The distance between each two adjacent circles is 1 km (the radius of the small circle is 1 km). If the boat C At 2 km due south of the cruise ship, the following description of the positions of boats A and B is correct (D)

A. Boat A is 60° north by east of the cruise ship and 3 km away from the cruise ship

B. The cruise ship is 60° north by east of boat A and 3 km away from the cruise ship

C. Boat B is 30° north by west of the cruise ship and 2 km away from the cruise ship

D. Boat B is 60° north by west of the cruise ship and 2 km away from the cruise ship

7. Arrange the positive integers according to the rules as shown in the figure. If the ordered real number pair (n, m) represents the nth row, the mth number from left to right, such as (4,2) represents 9, then The ordered number pair representing 58 is (A)

A.(11,3) B.(3,11)

C.(11,9) D.(9,11)

8. In the plane rectangular coordinate system, Kong Li plays a chess game. The method of movement is: the chess piece starts from the origin, moves 1 unit to the right in the first step, moves 2 units to the right in the second step, and moves 2 units to the right in the third step. Go up 1 unit, go 1 unit to the right on the 4th step...and so on, the nth step is: when n is divisible by 3, then go up 1 unit; when n is divided by 3, When the remainder is 1, go 1 unit to the right; when n is divided by 3 and the remainder is 2, go 2 units to the right. When the 100th move is completed, the coordinates of the chess piece's position are (C)

A.(66,34) B.(67,33)

C.(100,33) D.(99,34)

9. Xiaogang’s home is located on the 16th floor of Building A of a residential building, which is recorded as A16. According to this method, Xiaohong’s home is located on the 10th floor of Building B, which can be recorded as B10.

Determine the position PPT, the third part: expand, explore and break through

13. As shown in the picture, the school organized a hand-in-hand activity. Once, Xiaohong attached a schematic diagram of the surrounding environment of her school to a letter sent to her friends to introduce the location of her school. For the school:

(1) What facilities are located due east? What other data is needed to clarify the location of these facilities relative to the school?

(2) What are the facilities closest to the school? In which direction of the school is it? Are there other facilities in this direction? How to distinguish them?

(3) What data is needed to determine the location of the TV tower relative to the school?

Solution: (1) There are supermarkets and art centers due east. To determine the location of these facilities relative to the school, distance is required.

(2) The closest facility to the school is the children's park, which is 30° south-west of the school; there are also farmers' markets in this direction; they are at different distances from the school.

(3) To determine the position of the TV tower relative to the school, the azimuth angle and distance are required.
