We saw that superposition is a useful method to test congruence of plane figures. We
discussed conditions for congruence of line segments, angles and triangles. You can now
try to extend this idea to other plane figures as well.
1. Consider cut-outs of different sizes of squares. Use the method of superposition to
find out the condition for congruence of squares. How does the idea of
*corresponding parts' under congruence apply? Are there corresponding sides? Are
there corresponding diagonals?
2. What happens if you take circles? What is the condition for congruence of two
circles? Again, you can use the method of superposition. Investigate.
3. Try to extend this idea to other plane figures like regular hexagons, etc.
4. Take two congruent copies of a triangle. By paper folding, investigate if they have
equal altitudes. Do they have equal medians? What can you say about their perimeters
and areas?
