"Determination of the Position of Objects" Transformation of Graphics and Determination of Position PPT Courseware 3

What have we learned before about determining location?

⑴Up, down, left, right, front, back

⑵East, south, west, north, southeast, southwest, northeast, northwest

⑶ Number pairs (which column, which row)

Xiao Ming's home is 300 meters north of the school, and Xiao Hui's home is 500 meters southeast of the school. Draw the drawing to the given scale. (Scale 1:20000)

group discussion:

(1) Where should we first use the observation point to determine the location of the two places?

(2) Draw a cross diagram. What issues should you pay attention to when painting?

(3)What to do next?

First determine ( ), then ( )

(4) Work in groups to calculate the distance on the map and mark the locations of the two students’ homes. (How to divide work in a group to calculate faster and complete more efficiently)

Steps for drawing to a given scale:

1. Determine the observation point.

2. Draw a cross diagram. (Generally, the intersection point is determined as the observation point)

3. Determine the direction.

4. Calculate the distance on the map according to the scale.

5. Drawing (measuring distances, tracing points, marking)

Using Chen Xing's position as the observation point, can we determine the positions of Xiao Ding, Xiao Lin, and Xiao Fang?

⑴Xiao Ding is 8m away from classmate Chen Xing.

⑵Xiao Lin stands to the south of classmate Chen Xing.

⑶Xiaofang is located 10m due west of classmate Chen Xing.
