Cart vs. Trolley
The regional overlap is strongest for shopping carts/trolleys, serving carriers, and the online shopping-basket metaphor. Outside those senses, “cart” and “trolley” can name different vehicles or equipment.
For shopping and some wheeled-carrier or service contexts, US English often uses “cart” where UK English uses “trolley.” The words are not universal synonyms because both have additional local and specialized senses.

Quick tests
Decision test
Are you referring to the ordinary shopping/service wheeled carrier or online shopping basket?
If yes: Use “cart” for US wording or “trolley” for UK wording.
If no: For hospital, transit, vehicle, or other senses, identify the actual object and local terminology.
Caveat: Do not teach “cart” and “trolley” as universal synonyms; their non-overlapping senses vary by region and domain.
Examples
Put the groceries in the shopping cart.
US English commonly uses “cart” for the wheeled shopping carrier.
She returned the trolley after unloading the groceries.
UK English commonly uses “trolley” for the same shopping object.
The hospital trolley was moved into the corridor.
This “trolley” sense is not simply a regional synonym for every “cart.”
