๐ฏ Points, Lines, and Line Segments
Welcome, little mathematician! Today we will learn about three special shapes in geometry!
๐ด What is a Point?
A point is:
- โจ The smallest shape in geometry
- ๐ Shows only a location (a spot)
- ๐ Has no size - no length, no width, no height!
- โ๏ธ We draw it as a tiny dot
๐ Naming Points:
We use CAPITAL LETTERS to name points!
Examples: Point A, Point B, Point C
Interactive visualization โ available in the full lesson
๐ Real-Life Examples of Points:

โ๏ธ What is a Line?
A line is:
- โก๏ธ A straight path that goes on forever
- ๐ Has no beginning and no end
- ๐ Is perfectly straight
- ๐ Goes in both directions forever!
๐ Naming Lines:
Way 1: Use two points on the line: Line AB or Line BA
Way 2: Use a lowercase letter: line m, line n
โ ๏ธ Always draw arrows on BOTH ends to show it goes forever!
