The ancient Egyptians had a neat way to construct right angles. They would make a long rope with knots to
make 12 equal sections.
When they stretched the rope into the triangle shown below, they always got a right angle. This was useful
when planning the pyramids, for example.
If we apply the Pythagorean Theorem to the Egyptian knots we can see that 32 + 42 = 52.
Which of the sets of three numbers listed would also let you form a right angle in this way?
