the pythagorean theorem
Not all lengths make a right triangle
There isn’t a length that can complete Sam’s design for an 11 - 9 - ? jump and
give a perfectly vertical upright. Size 7 is too long and size 6 is too short. It
seems some lengths can make right triangles and others can’t.

Not by much but
only exactly 90º is
a right angle, 91.2º
doesn’t cut it!
Less than a

Whoa. So not every jump is
viable? That’s all right—let’s
just make a list of the ones that
we CAN build.
How could you create a list of jumps that can be
built from the Kwik-klik pieces?
