A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

This is a science community. We use the Dawkins definition of meme.
If you're talking about straight lines, then yes, that's how you define a convex shape. If any uninterrupted path can be taken, then the OP shape does satisfy the condition.
Edit: just read the other comments and I see the problem was that you thought the internal angle shown for reference on how the shape was built is part of the shape. It's not, just the thicker lines define the shape shown. The little crossmarks that show equal sides are also not part of the shape.
