ACTIVITY- MID-POINT THEOREM

Objective
To verify that in a triangle, the line joining the mid-points of any two sides is
parallel to the third side and half of it by paper folding and pasting.

Prerequisite Knowledge

1. Concept of angles, triangles and mid-points.
2. Concept of corresponding angles: If a transversal cuts two straight
lines such that their corresponding angles are equal, then the lines are
parallel.

Materials Required
Glazed papers, a pair of scissors, pencil, eraser, gluestick, white sheet.

Procedure

1. Draw ∆ABC on the yellow glazed paper of any measurement and paste
it on white sheet.
2. Find mid-points of the two sides (say AB and AC) of a triangle by paper
folding. We obtain D and E as mid-points of AB and AC respectively in 1st
triangle.
