Summary

Description
English: Demonstration of rigid and flexible graphs. Graphs are drawn as hinges connected by rigid rods. The cycle graph C4 drawn as a square is flexible because a force can tilt it over into a parallelogram. The complete graph K3 drawn as a triangle is rigid because no force applied in any direction will cause it to move.
