Triangle Experts

We solve triangles one by one.
We know the laws the theorems and the angle sums.
Triangle experts we'll become.
We solve triangles one by one.

Yo this is 2 Pi coming at you like Kris Kringle.
I'm bringing you gifts to help you solve triangles.
I got gift bags filled with all kinds of perks,
for turning youngsters into triangle solving experts.
If you can solve the tri- then you can solve the poly-.
You'll be knocking out problems like your last name was Ali.
See, the triangle is the mother of all polygons.
If you can solve her then your math game is tight like Lebron's
But if you can't solve triangle then your a rookie my friend.
You're gonna drop the ball, "You can say that again."

[Chorus]

The first tool in my bag is the Triangle Sum Theorem.
You get 180 each and every time you add them.
If you rip up your triangle and line up your vertices,
They'll form a straight line because they're supplementary.
Or if you have two angles you can find the third,
Subtract their sum from 180 and you got it,"Word"
"Word word, come on people keep solving those triangles"
The 2nd told in this bag is eponymously named after the Greek Mathematician from whom it came.
For any right triangle the hypotenuse squared equals the sum of the legs squared
Now you're prepared the find the 3rd side of any right triangle you see
Use the Pythagorean theorem and your A, B, C's
"Please we solve triangles on our way to diplomas"
Podemos hablar de triagulos in dos idiomas.
[Spanish verses by Chico Brillo]

And then there's Soh Cah Toa, the trigonometric quotients
Used to solve for sides and angles like magic potions
H is the hypotenuse, the longest side
O's the side opposite angle theta each time
A is the side that always touches angle theta
Like the bottom jaw of an hungry alligator
This tool only works on right triangles keep that in mind
But the next two can be used on triangles of any kind
The law of sines' a ratio that's tested and tried
It states, 'The sine of an angle over the opposite side,
equals a ratio that's consistent for all three pairs."
But given Angle Side Side there's ambiguity there.
When given Side Angle Side the Law Of Cosines your tool.
Just sub simplify then you take the square root.
The value you get is the length of side C.
Master these five tools a triangle expert you'll be
[Chorus]
