Points are the most basic concept in Geometry.
They are represented by a “X” and labelled by a Capital letter.
A point describes a location.

A line can be drawn by points
What is the difference between Line and Line Segment ( 線段 )?
Line segment has end-points

Naming a line: By 2 points on the line By a letter
Type of lines Straight line (直線 ) Curved line ( 曲線 )

Naming a plane: By corners (vertex 頂點 ) in either
clockwise or anti-clockwise order
By a Capital letter

We can learn a lot about geometry from the art of origami (摺紙 )
Let’s try to fold the paper:
Is the crease ( 摺痕 ) a point, a line or a plane?
![Page 9: Form 1 Mathematics Chapter 6. Lesson requirement Textbook 1A Workbook 1A Notebook (and folder) Before lessons start Desks in good order!](https://reader035.fdocuments.in/reader035/viewer/2022062409/5697c0101a28abf838ccb44e/html5/thumbnails/9.jpg)
Consider ABD and BCD are two different planes.
When two planes intersect each other (相交 ), they form a line.
We called it line of intersection
![Page 10: Form 1 Mathematics Chapter 6. Lesson requirement Textbook 1A Workbook 1A Notebook (and folder) Before lessons start Desks in good order!](https://reader035.fdocuments.in/reader035/viewer/2022062409/5697c0101a28abf838ccb44e/html5/thumbnails/10.jpg)
Let’s continue to fold the paper:
When two lines (AC and BD) intersect each other, they form a point.
We called it point of intersection

Think about the followings:
Is it possible to have two planes that do not intersect each other?
Is it possible to have two lines that do not intersect each other?
