Congruency means that two figures or items are exactly the same size and shape. Where in life would it be vitally important for two or more items to be congruent?

My first thought would be wheels on a car... does anyone else have any better ideas?

Thanks!!! :)

Bridge parts

Thrust in multi engine rockets

Airplane wings, landing gear...

The outriggers (Hydraulic jacks on arms) on mobile cranes..

The footings of buildings

While it feels really weird, you can drive a 2 wheel drive car on different sized wheels. Different sized wheels on a 4 wheel drive car will break the drive system.

Different sized wheels on a skateboard would make it imposable to ride.

I just thought of another one: the legs of a table...

The wings on windmills

Thanks so much Ken!! Those were great ideas. I really appreciate it! :)

THANKS KEN!

thanks ken!

Thanks Ken
