Today's lesson was on Beginning Proofs, which will be the foundation of this trimester.

Theorem- a mathematical statement that can must be proved.

Theorem Procedure

1. We present a theorem or theorems.
2. We prove the theorem(s).

Note-Although all theorems presented can be proved, we [the textbook] shall omit the proof of

certain theorems.

3. We use the theorems to help prove sample problems.

4.You are then given the challenge of using the theorems to prove homework problems. Theorems will save you much time if you learn them and then use them.

Theorem 1 If two angles are right angles, then they are congruent.

If (given), then (prove).
