• hypotenuse song- right triangles- pythagorean theorem-geometry

  A song about the hypotenuse of right triangles. Also has short lesson on the Pythagorean theorem at the end.
  
  See more of my math and science resources at:

  LYRICS:
  Hypotenuse, (right triangle)
  Is the longest side... (right triangle)
  Hypotenuse, (right triangle)
  Is the longest side...(right triangle)
  
  It's not the shortest,
  Or the next,
  It's the longest side,
  Like the kiddies like to ride,
  Like a playground slide...
  Obtuse, they must be playin',
  They won't wanna' tangle,
  Acute's don't have hypotenuse,
  Like a right triangle...
  
  Acutes and obtuse,
  Have no hypotenuse now,
  No angles of 90 degrees...
  Acutes and obtuse,
  Have no hypotenuse now,
  No angles of 90 degrees...
  
  Hypotenuse, (right triangle)
  Is the longest side...(right triangle)
  Hypotenuse, (right triangle)
  Is the longest side...(right triangle)
  
  It's the hottest of the hot,
  It's the hottest one,
  It's so burning like a flame,
  Like the hot summer sun...
  Measuring degrees,
  90 is the angle,
  Opposite hypotenuse in a right triangle!
  
  Opposite 90, yes, opposite 90,
  Yes,opposite 90 degrees...
  Opposite 90 yes, opposite 90
  Yes, opposite 90 degrees...
  
  Hypotenuse, (right triangle)
  Is the longest side...(right triangle)
  Hypotenuse, (right triangle)
  Is the longest side...(right triangle)
  
  Pythagoras my man,
  Discovered a math theorem,
  You didn't live in ancient Greece,
  I know you couldn't hear him
  A rule of right triangles,
  Pythagoras, devised,
  A squared plus B squared,
  Is what he advised!
  
  A2 + b2 = C2
  Hypotenuse is letter C
  A2 + b2 = C2
  Hypotenuse is letter C
