# Pythagorean Theorem Rap

Chorus:
90 degrees make up a right angle
corner of a square or a rectangle
forms a type of triangle that’s right
gonna rhyme about triangles if you don’t mind
in total there are a few different kinds
isosceles: 2 sides are the same
scalene: 3 unequal of a frame
one special shape is everywhere though
look in a corner, right triangle bro
3 angles, one of which is 90 degrees
understand this and you’ll hold all the keys sides are called two legs and hypotenuse
hypotenuse gives the right angle juice
from the right angle on the opposite side
as the longest side it’s got a lot of pride
Chorus
other angles smaller than 90 degrees
all add up to 180 don’t you see
leg can be opposite or adjacent
solve trig problems, don’t be complacent
need to use sine, cosine and tangent
properties of an angle, understand it
if not don’t worry too much
just use SOHCAHTOA to  get you through the clutch
sine is opposite over hypotenuse
right angle expert now you can represent
Chorus
with a calculator and limited info
you can figure out sides and angles bro
the way to measure ‘em when you see ‘em
formula called the Pythagorean theorem
let’s say hypotenuse is “c”
and the legs are “a” and “b”
in every right triangle everywhere
a2 + b2 = c2
Pythagoras was an old school G
in Greece he lived around 500 BC
wrote the first proof to the theorem
beat India to it and the Babylonians
Chorus
let’s say you gotta build a ramp 3 feet tall
start it four feet from the wall
will let you know how much wood you need
shred that baby at just the right speed
just plug in 3 and 4
into the Pythagorean theorem, nothing more
take the square root of 25
length is five, now skate and stay alive
if a plane takes off at 40 degrees
how high is it if it travels 2000 feet
use SOHCAHTOA to find opposite
sine of 40 times 2000, that’s it
Chorus
suppose you need to find a side
hypotenuse is 13, other is 5
find the missing leg by yourselves
Pythagorean theorem says that it’s 12
