I don’t see right angles

They’re marked with tiny grey squares. But to be more precise, any line that goes through the center of a circle will intersect the circle at a right angle.

It’s constructed like this:

All 4 sides of A and B are right triangles. Same with C and D. Then we erase some lines and:


This shape. Except mine doesn’t have for equal length sides, theirs does.

Now, this is breaking a Euclidean postulate. Specifically that the lines aren’t straight. I’m not sure if “angles must be measured from inside the shape” is also a Euclidean rule. I think it’s a natural side-effect of the Eucliduan postulates which makes it a Euclidian correlary.

Point is, that this is a pretty standard Non-Euclidian shape, specifically a non-Euclidian square. This is what Lovecraft expects you to be afraid of.

Well I know at least one person in the world that would be afraid…
