Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Watch this and it should make more sense what is happening.

Then after pulling the face forward (as I did in the video above) I mentioned the edge may look odd because their normals were soft and to select Normals>Harden Normals (which I had put on my shelf bar) so the edges have a faceted look and are easier to see.
When you add polygons maya will look at the angle between faces and if it is below a threshold (usually 30%) it will soften the normals of the edges between the two polygons to give a smoothed appearance. Since the final intent is to smooth the overall model I like to harden all the edges from time to time as I model to give the model a faceted appearance so that it's easier to see the edges without having to turn on wire frame on shaded mode.
I think that might be what you are referring too.
There are a small number of modeling tools that I use alot that I pull to my shelf bar and harden and soften normals are two of them.
I also have center pivot, freeze transform, and delete history on the shelf. These are all under the modify tab.

Hang in there and we'll get this worked out.
It's not unusual to have to start over a lot when you are just learning. This is a beginner level tutorial but I did try to include as many techniques as I could along the way.

Can you give me the time code and the video part you are on. I'll take a look at that section and can walk you through it.

You have the edge running through the vert creating a triangle. If you go to time code around 1:30 and play through again you'll see that I use the cut faces tool and say something like place the edge "just inside of this vert" indicating the inner most verts on those sections that form the X shape.
When you get to the part just before I make the bend around time code 3:38 I say something like "now before we bend the side lets go around and look to see if we have created any triangles" and "everything is all quads so let continue".
I have grabbed a screen capture so you can see the difference of the version in the video and yours around that point so you can see the issue.
Also you seem to have missed the part where I adjust bottom edges of that part the forms the X inward to create bevel. The sides on yours are coming straight down.

As a general rule triangles and ngon (polygons with more then four sides) should be avoided. This rule can sometimes be bent. But as a beginner I would suggest you try to stick with quads.
There is a triangle in the above screen grab from the tutorial for instance that would not be a problem there is also an ngon (see the image below) since this tut was targeted for beginner level at a later point in the tutorial I add a edge to make those into a quads.
If it's your own personal project and you are aware of how the model is going to be rendered and used such as will it be deformed or not then you can save some time and effort by leaving an occasional tri or even an ngon in the model but many would argue this is just bad form. I am of mixed opinion on this so I will leave it to you to decide. However, as you are learning I'd strongly suggest to stick to avoiding tri's and ngons.
In studios they will generally prohibit ngons and tri's even if they do not present a problem. There are a number of very good reasons that they have this rule. One of the most obvious is that in a studio many artists may have to work with your model as it moves through the pipeline. If someone had to adjust the model later in the pipeline that innocuous tri or ngon could become a problem.

The tutorial is beginner level but it has techniques that are designed to prepare you for the next level. So it's a step beyond the typical beginner tutorial that basically stuffs primitive shapes into each other. (smile).
I try to do my best to explain each step.
