You cannot display an alert message from a trigger.

From trigger you can stop the deletion altogether based on your requirement. But you cannot provide the functionality of showing an alert message and then on click of okay carry out the delete operation.

If the user is trying to delete a record from the salesforce UI then generally an alert message(technically it is not an alert but a confirm message) is shown by Salesforce by defult.

You can throw the exception message to say "You need to confirm the deletion of this record before deleting by ticking 'Confirm Deletion' on the record" The user would then have to tick the "Confirm Deletion" tick box on the record and then try and delete the record again.
