Greece is not a simple shape, but it can be described as having a roughly triangular outline.

Here's a more detailed breakdown:

* Mainland Greece: The mainland portion is shaped like a long, thin triangle, pointing south towards the Mediterranean Sea.

* Islands: Greece has thousands of islands, adding complexity to its overall shape. The islands are scattered across the Aegean Sea, forming a sort of crescent shape.

* Peninsulas: The mainland also features several peninsulas, adding to its irregular shape.

So, while it's not a perfect triangle, the overall outline of Greece is roughly triangular with a lot of detail and complexity.
