By paper cutting/pasting verify "diagonal of a paralleogram divides it into two triangles of equal areas.
Dotted paper, ruler,sketch pen, pair of scissors
Step 1 Draw a parallelogram ABCD on a dotted paper.
Step 2 Join diagonal AC.
Step 3 Cut the parallelogram.
Step 4 Cut along the diagonal AC.
Step 5 Place triangle ABC on triangle ADB such that AD coincides with BC, AB coincides with CDStep 6 Repeat the activity for the other diagonal
1.Triangle ABC completely covers triangle CDA.
Result:Diagonal of a parallelogram divides it into two triangles of equal areas.
