Write 4–6 sentences explaining why it is important to have precise definitions in mathematics. Choose five terms, some from geometry and some from other areas of mathematics and give a precise definition of each. Then change each of those definitions so that it still describes the term but not precisely enough to avoid ambiguity. Formulate counterexamples, with sketches when feasible, that show how things could satisfy the less precise definitions but not match the intended terms.
