I am trying to create a 90 degree angle from two pieces of wood so that I can eventually create a squared enclosure. I have cut two pieces of wood at 45 degrees with a circular saw's angle adjustment.
However, when I try to join the pieces of wood, they only meet at their tips and not throughout the slope of the cut (see photo below). Because of this, I can't figure out how to nicely join them together while ensuring that they will have a 90 degree angle when they are merged.
What is the recommended way join wood in this way to create flush 90 degree angles for a squared enclosure? Is it possible to do this with a circular saw?

You need to adjust your circular saw to an actual 45 degree angle, not to where the scale markings say '45'. Your speed square will do the trick.
(Or redesign for butt joints and skip the bother of a circular saw for 45s like that...)
edit to add, I tend to avoid cuts like this with a handheld circular saw because they are hard to do well, but you can improve the cut by concentrating on keeping the large part of the shoe (aka sole/deck) flat on the wood, and using something like your speed square to guide the saw to a smooth 90 degree cut.
