E Similar situation on the tou.rer shown above. The usage of blocks required to finish a triangle is verg huge. Therefore the tou,rer cannot be buitt higher as there uias a block amount limitation. comparing to the tower on the last page, this tower is even more stable. Since triangle onlg consists three dimensions, and circle has innumerable dimensions, blocks will alwags have better surface contact and connection with each other r^rhen building wa[[s in a shape of triangle because there is onlg three turning point in the entire construction. The fortifging contact area ensures the efficient composition of loads and forces.
