They’re also not actually right angles, as the curvature starts departing from the angles origin. They may be approximately 90, down to many many small decimal places, but they are not 90.

That’s not accurate. If you are measuring the angle of a line intersecting with a curved surface, you measure against the tangent at the point of contact. It can be and still is exactly 90 degrees.

And that polygons should only consist of straight lines.

Yes sure, in Euclidean geometry, but this is clearly keyhole shaped geometry.
