To answer your question pedantically, probably nothing; with enough time and effort, you could bend either tool to perform the general duties of the other. Terraform is capable of injecting and running shell scripts; Ansible can likewise interface with AWS and other cloud providers (or your own hardware). As sibling commenters have noted, that’s simply not the ideal primary use for each tool.
