Who is Correct: SCENARIO

Sarah claims that any three lengths will determine three sides of a triangle. Sam does not agree. He thinks some combinations will not work.

WHO IS CORRECT? Remember, you need one counterexample to

disprove a statement.Sam claims that he can just look at the three

lengths and know immediately if they work. Sarah is unsure. She decides to explore this for herself.

Steps 1 and 2

To begin you will need a piece of pasta. Break the pasta at TWO random points so the strand is divided into three pieces.1) Try to form a triangle from your three pieces

of pasta.2) Measure each of your three pieces in
