A square is a four sided figure - each side is equal in length and adjacent sides are perpendicular.

Those two corners are not 90 degrees near the circle area. In retrospect, none of those corners look like they are 90 degrees.
You can't know everything, but you can know anything.

To be honestly fair, the picture looks like a chess piece ♟️. 😀
In both The Hunger Games and in gambling, may the odds be ever in your favor. :D

First, technically, none of the angles are "right angles"; their tangents may be right angles, but that's different.
Second, the four sides of a square have to be line segments.

Isn't a curve a line? The equator is a straight line that curves around the globe, no?

Not in Euclidian geometry. A "straight" line cannot curve.
I am not exactly sure what the "strict" definition of line is, but I am pretty sure it is something like, "A path such that, given any two different points A and B on that path, the path from A to B that has the shortest distance is entirely on the line's path."

There may be a bit about all parts of a line segment are coplanar, for all planes including the endpoints of the line segment.
(This does not hold true for arcs.)

If a line extends infinitely in both directions, and we live on a globe, aren't all lines circles ?
If I start at Point A and walk in a straight line, I'll eventually end up back at the same spot.
What am I missing?

The fact that you are not walking on a "straight line" if you are on a sphere - the line curves along the boundary of the sphere.
Think of it this way: shoot, say, a laser beam from the surface of the earth, parallel (well, tangent) to the surface. Would it go around the earth and return to you, or would it go out into space?

d2y/dx2=0 is good enough in Cartesian, no?
