I find right angles fascinating. The right angle is the exact fourth part of a full circle. It is especially central in geometry, building and so many other areas. If pieces of furniture or other things are constructed in a right angle, they can be stacked well or otherwise combined with other things, etc. The transmission of force is also very good with a right angle or the resistance is then optimal. In measurement, it is optimal when it comes to cutting quantities - so the part is convincingly good. Now you can ask whether there are also wrong or left angles if there is obviously a right angle. I don't really think so. But all other angles do not have the advantages that a right angle has. Perhaps you find all this banal - but I, for one, am fascinated by this law. Do you also have such natural phenomena that amaze and fascinate you?
I wish you an extraordinary day!
