Sam’s sketched up another two jumps which she hopes can be

built from the Kwik-klik parts.

Use the same pencil and ruler construction technique to find out

and ruler solution

This line is 10cm

exactly.

This line is

6cm exactly.

We need to use an

upright of size 6.

This line is 9cm exactly.

None of these lines are

exactly 11cm!

There doesn’t

seem to be an

upright that

would fit here....
