the pythagorean theorem
Standard-sized-quick-assembly-what?!?
Sam’s found a supplier for giant construction kit parts. Kwik-klik makes
parts which are just like construction kit toys you might have seen or played
with when you were younger, but on a much bigger scale.
1 2 3
A piece with length
3 has four holes.
Length 1 Length 8 Length 2.5
This doesn’t
work.
The lengths are
always whole numbers.
You can change
this angle.
The bars get fixed
together with a bolt
through the holes.
So easy, anyone can do it! But Sam’s first ramp has a major problem…
Try drawing a 3cm line with
a dot at the start and the
end, as well as each cm.
The pieces have holes in them
at evenly spaced intervals.
Because there’s a hole on either end,
each piece has one more hole than
the length it represents.
The parts come in tons of sizes,
from size 1 upward, but always
as whole numbers.
You can’t have a size “two and a half ”
part.
To build stuff, you just bolt the
parts together through lined-up holes.
The pieces can pivot to any angle around the
bolt, so you can swing them into any position
you need.
We don’t count the
length of the extra
bits on the ends.
