"Determine the position (2)" Determine the position PPT

Part One: Review Import

What did we learn in the last lesson?

Learned to use direction and distance to determine the position of objects

Think about it, how can you get back to the base camp from Daming Mountain? What methods do you have?

Determining the location PPT, part 2: exploring new knowledge

1. According to the situation map, how can Lele return to the base camp from Daming Mountain?

(1) Where does Lele want to go from?

(2) How many conditions are needed to express the relative positions of these two places? Can one condition be enough?

(3) If not, how many conditions need to be used to determine their relative positions?

(4) Can you describe it in words?

① Return to base camp from Daming Mountain. First, we need to connect Daming Mountain and the base camp with a line. Returning to the base camp from Daming Mountain, Daming Mountain is used as the observation point. Then draw the coordinate system, mark the direction, measure the angle, and then measure the distance from Daming Mountain to the base camp.

② The position of an object cannot be determined by angle alone, and the position of an object cannot be determined by distance alone. The two must be combined.

Summary: Use direction and distance to determine the position of an object.

Determine the position PPT, part 3: Consolidation exercises

1. (1) How to get to the school from Qisijia?

(2) Use two methods to indicate the location of the school.

(1) 4.3x100=430 meters

Answer: 45 to the east by north. Walk 430m in the direction to the school

(2)90. -45. =45.

Answer: The school is located at 45 North by East of Qisijia. The direction is 430 meters; the school is 45 meters east by north of Qisijia. direction 430 meters.
