🔢 1. Points, Lines, and Curves
Points
A point is a position in space. It has no size, only location.
A point is represented by a dot.
Lines
Straight Line
A straight line is the shortest path between two points.
Curved Line
A curved line changes direction smoothly without any sharp turns.
Drawing Lines
To draw straight lines, we use rulers. For curves, we can draw them freehand or use tools like compasses.
