Rhombi, a la Shmoop.

00:07

The Richardson Family Rhombus has been passed from generation to generation…

00:11

…and is rumored to bring bad luck to all of its possessors.

00:15

There’s just something shifty about the rhombus’ perfect shape.

00:19

On this segment, we inspect the fabled rhombus to see if any connection can be made between

00:23

its geometry and its shady history.

00:26

This is “Behind the Diamond.”

00:29

Like all rhombi, the Richardson Family Rhombus is a parallelogram…

00:33

a quadrilateral with two pairs of parallel sides… with all four sides congruent.

00:38

This particular characteristic became a source of terror for the wealthy Wurster family…

00:43

…who eventually went insane because they could not tell if the Rhombus was in the same

00:47

position they had left it.

00:49

Had it been flipped over during the night? Was it facing the other way? No one knew.

00:55

Another shared characteristic with other rhombi was its diagonals, which were perpendicular,

01:00

and bisected all four of its vertex angles.

01:03

This eventually led to the mental degeneration of the gem expert Sir Pipswhat…

01:09

…who spent his entire life attempting to break the famed Rhombus into two perfectly

01:13

congruent isosceles triangles.

01:16

He could never actually bring himself to touch the priceless rhombus,

01:19

and ultimately ended up in a mental hospital.

01:23

The Richardson Family Rhombus is currently in the possession of a family

01:27

who refused to be mentioned on this program.

01:30

Will the Rhombus’ perfect geometry get the best of them?

01:33

Find out next time, on a future installment of “Behind the Diamond.”
