  • Cyberchase: Proving Hacker Wrong

    Math → Mathematical Logic → Proofs
    Math → Mathematical Logic → Counterexample
    Math → Geometry → Triangles
    Jackie, Matt, and Inez set out to prove that Hacker doesn't deserve to be the ruler of Cyberspace. They try to find a counterexample to his statement that "you can always make a triangle out of any three rods." After some experimentation, they discover that one long rod and two short rods do not connect and therefore do not make a triangle. They present their findings during the debate.
