"Determine Location" Position and Coordinates PPT

Description

"Determine Location" Position and Coordinates PPT

Part One: Learning Objectives

1. Understand that determining the position of an object in a plane generally requires two pieces of data. (emphasis)

2. Flexibly use different methods to determine the location of objects. (difficulty)

Determining the position PPT, part 2: teaching new lessons

Determine the position of a point using ordered pairs of real numbers

Thinking 1 The teacher is looking for a student in the class. Do you know who it is?

Tip 1: Given only one data "column 2", can you determine who the student the teacher is looking for is?

Tip 2: Given two data "column 2, row 3", can you determine who it is?

Thinking 2 How much data do you think is needed to determine a location?

Do it

(1) What is the difference in meaning of the "6" in "No. 3 in row 6" and "No. 6 in row 3" on the movie ticket? Can you find their corresponding locations?

(2) If "No. 3 in row 6" is abbreviated as (6, 3), then how to express "No. 6 in row 3"? What does (5,6) mean? What about (6,5)?

(3) In a cinema with only one floor, how much data is generally required to determine a seat?

azimuth method to determine location

Example 1: The picture below is a schematic diagram of the confrontation between the enemy and our ships in a certain naval battle (1cm in the picture represents 20 n miles). For our submarine O:

(1) What targets are there in the direction of 40° north by east? What other data is needed to determine the position of enemy ship B?

Solution: (1) There is enemy ship B and a small island; we also need the distance between enemy ship B and our submarine O.

(2) How many enemy ships are 20 n miles away from our submarine?

(2) There are enemy ship A and enemy ship C.

Determine the position PPT, the third part: practice in class

1. In the plane, the following data cannot determine the position of the object ( )

A. No. 5, Floor 3 B. 40° north by west

C. No. 30 Jiefang Road D. 120° east longitude, 30° north latitude

2. When a maritime disaster relief ship goes to rescue a burning ship in a certain sea area, it needs to be determined ( )

A. Azimuth B. Distance

C. The nationality of the ship on fire D. Azimuth and distance

Determine the position PPT, part 4 content: Class summary
