Question 707457
They could use the rope to measure out 3 units for one leg and 4 units for the other leg. Then they would use the rope to measure 5 units from one endpoint of the leg and draw a circle. That would be used to construct a 3,4,5 side length triangle.


Since 3^2 + 4^2 = 5^2 by the pythagorean theorem converse, we know that the triangle formed (3,4,5) is a right triangle.


They would then be able to scale either leg to whatever lengths they wanted once they had the right angle.
