  3. 2-2Biconditionals and Definitions

  4. Biconditionals When both the conditional and its converse are true, the statement is called a biconditional. You can write a biconditional as a statement using if and only if:

  5. Example If three points are collinear, then they lie on the same line. true If three points lie on the same line, then they are collinear. True Biconditional Three points are collinear if and only if they lie on the same line.

  6. Super Fun Activity Pick an object in the room or a word and write a definition of it. Be creative. Don’t be lame.

  7. What made a good definition?

  8. Good Definitions • Clear terms, that are already defined • Precise (don’t use vague words like large, sort of, almost) • It’s reversible (you can write it as a biconditional)

  9. Examples: • A triangle has sharp corners. -imprecise word: sharp -no reversible • A square is a figure with four right angles. • Counter example
