Description

"Plane Cartesian Coordinate System" Position and Coordinates PPT Courseware 5

Review old knowledge

1. Definition of "Plane Cartesian Coordinate System":

In a plane, two mutually perpendicular number axes with a common origin form a plane rectangular coordinate system.

2. How to establish the "Plane Cartesian Coordinate System":

(1) Establish the origin O;

(2) The right direction through point O is the positive direction, and a number axis is established at the horizontal position called the x-axis or horizontal axis;

(3) The orientation through point O is the positive direction, and a number axis is established at the vertical position called the y-axis or vertical axis.

Summary of new knowledge

Coordinate characteristics of "point on a straight line parallel to two axes":

(1) Points on the straight line parallel to the x-axis: the ordinates are the same;

(2) Points on the straight line parallel to the y-axis: the abscissas are the same.

Class summary

1. Coordinate characteristics of "points on a straight line parallel to two axes":

(1) Points on the straight line parallel to the x-axis: the ordinates are the same;

(2) Points on the straight line parallel to the y-axis: the abscissas are the same.

2. Coordinate characteristics of "four quadrants, origin and points on two axes":

3. Coordinate characteristics of “a point symmetrical about the coordinate axis”:

(1) The coordinates of the point that is symmetrical about the x-axis: the same as the transverse direction and the opposite direction as the vertical direction;

(2) The coordinates of a point that is symmetrical about the y-axis: the same as the horizontal and vertical directions.

4. Coordinate characteristics of "point symmetrical about the origin":

The coordinates of a point that is symmetrical about the center of the origin: reverse both horizontally and vertically.
