I realize that there are a bazillion questions on tex.stackexchange about right angle symbols, but all of them (that I can find) seem needlessly complicated, and it's taking me a long time to make sense of the answers.
My question should have a very simple answer. Suppose I have two line segments meeting at a right angle in tikz. Accordingly, I would like to add a right angle symbol to the diagram.
This can be done "by hand" using a very painstaking process. But surely there's an automated way to do it.
Thanks!
