Individual Activity

Objective: To know the number of lines passing through (a) one point and (b) two points
Material required: Drawing sheets, a pencil, a ruler

Demonstration:
Step 1: Mark two points P and Q on a white sheet P Q
of paper.
Step 2: Fold the paper so that the crease passes Q
through the point P. P
Step 3: Keep folding the paper in different directions
so that each crease passes through the point P.
Step 4: Repeat steps 2 and 3 for the point Q. P Q

Observation: There are unlimited lines passing through P or Q, but only one line that passes
through P and Q.
Inference: Infinite lines can pass through one point and only one line passes through two points.
