This is a standard way to draw geometric proofs, it's not at all unreasonable to assume straight lines and unrepresentative angles.

normally in a geometric proof, a right angle is a right angle

This was certainly not my experience in high school. An unlabelled angle could never be assumed. Only angles marked with a square could be taken as right angles.
