Is Polygon based on EVM?

Excuse me, I'm curious to know if Polygon is indeed built upon the Ethereum Virtual Machine (EVM)? I've heard of the compatibility aspect and its role in enabling seamless interaction between different blockchains, but I'd like to have a clearer understanding of Polygon's architecture in relation to EVM. Does this mean that developers can easily port their Ethereum-based projects to Polygon, leveraging the same programming languages and tools? I'm keen to grasp the intricacies of this relationship and how it benefits the broader blockchain ecosystem.
