So, it has finally come to this. Triangles. Oh, how I hate solving for missing angles and sides. Problems like that just confuse me. So, why, you might ask, am I devoting a single post to just triangles? Well, it’s complicated. Let’s just say that by challenging myself to write about it, maybe I’ll get some hidden insight into why triangles are, well, triangles. Yup, already failed the introduction. Anyway, I’ll try my best with this one. Here we go.
So, triangles. Let’s see. It has three sides. Duh. Oh there are, what I like to call, special triangles, since they each have a key characteristic that basically defines them. We first have the right triangle. Any triangle with a 90 degree angle has the right (Did you see what I did there?) to be called one. Then, there’s the acute triangle which are triangles only with angles that are less than 90 degrees. Acute… I can think of several pick up lines where I can use that word, which I’ll most likely forget. Lastly, there’s what is called an obtuse triangle. It is defined to be a triangle that has an angle greater than 90 degrees. All right. One down, two more to go.
Okay. What else about triangles is there? Oh, the Pythagorean theorem. With it, even people like me can figure out the length of the other sides just from knowing the length of one. If only I know how to use the equation, that is. It’s a² + b² = c². Each letter corresponds to one side, with c representing the hypotenuse. How you get one side is by moving things around until what you want is on one side. At least, that’s what my mom said. So, say you want the opposite side, or b in this case. All you need to do is the following:
b² = c² – a²
b = √(c² – a²)
Learned that from my bother. It took a while, but I got it down. Anyway, let’s move on. Hm. Oh, there’s this acronym that you must know if you’re working with triangles. It’s SOH-CAH-TOA. Conveniently, it helps you remember the three equations that will allow you to solve for the angle. Let’s see. There’s sin θ = opposite/hypotenuse, cos θ = adjacent/hypotenuse, and tan θ = opposite/adjacent. What? Don’t worry. I don’t understand much, too. All I know is that all the three sides have names, which are opposite, adjacent, and hypotenuse. The hypotenuse is always the longest-looking side of the triangle. On the other hand, the other two are named depending on which is nearer to the angle you are trying to solve for. It’s hard to explain but what I noticed is that the adjacent side seems to be the shorter of the two. As for what sin, cos, and tan are, well, let’s just say they are special numbers that relate each side of the triangle. Oh, SOH-CAH-TOA only works with right triangles. Make sure you remember that.
The last topic related to triangles that I want to discuss is, if it wasn’t already obvious from the image above, the Illuminati. It was the meme of 2014. Or was that 2013? Anyway, no one really knows what it is, or who started it. Some say that it’s some occult group that opposes the norms imposed by society. Others say that its some other-worldly being up above that is ALWAYS watching us. Yet others say that it’s just a prank, a ruse, or someone just trying to get attention. Either way, it’s a triangle with an eye in the middle, which could mean anything, really.
How about you? What do you think? Food for thought, I guess.
