1. Circles are geometrically similar  to one another and mirror symmetric. 2. This thus confirms that the original and normalized Euler spirals are geometrically similar . 3. He found for any ship and geometrically similar  model towed at the suitable speed that: 4. Therefore, the transition state will be more geometrically similar  to the reactants than to the products. 5. Convergent evolution can lead to geometrically similar  active sites while each enzyme has a distinct backbone conformation. 6. This of course would mean the two turbomachines being compared are geometrically similar  and running at the same operating point. 7. Objects that have the same shape or mirror image shapes are called geometrically similar , whether or not they have the same size. 8. Thus, congruent objects are always geometrically similar , but similar objects may not be congruent, as they may have different size. 9. Since the lengths and times have been scaled, the trajectories of the particles in the system follow geometrically similar  paths differing in size. 10. Though the two designs share a geometrically similar  hull shape, much about the " Orca "-class design is different from its forebear.
