Are Ceiling Tiles Asbestos

Does 12″ x 12″ ceiling tiles contain asbestos?
These ceiling tiles are interconnected to each other on 3 sides 4th side is nailed and they are in my basement. The house was built in mid 40’s. I do not know when these tiles were installed. I purchased the house 4 years ago. Thanks in advance.
its a good bet they are asbestos, wear a dust mask when removing them, plastic gloves an Tivec coveralls.
