1. Chapter Two Review Honors Geometry

2. Ch. 2 Test Topics  Perpendicularity  Write equations involving complements and supplements of angles (including both in same equation) (VIDEOS ONLINE!)  Write proofs involving comp/supp angles.  Write proofs involving complements/supplements of the same angle.  Write proofs involving complements /supplements of congruent angles. (VIDEOS)

3. Ch. 2 Test Topics (con’t)  Use addition/subtraction/mult/division properties in proofs. (VIDEOS)  Use transitive/substitution properties in proofs (VIDEOS)  One-Step Proofs (if/then statements or property name) (VIDEOS)  Two-column Proofs (VIDEOS)

4. Addition Property  CONGRUENT PAIRS of segs/angles  Given angles and segments that are smaller than the final angles/segs.  Need TWO pairs of congruent parts (or a shared part)  Angles/segs generally not divided into equal-sized pieces

5. Subtraction Property  CONGRUENT PAIRS of segs/angles  Given angles and segments that are larger than the final angles/segs.  Need TWO pairs of congruent parts (or a shared part)  Angles/segs generally not divided into equal-sized pieces

6. Multiplication Property  Must have CONGRUENT PAIRS of segs/angles.  Given segs/angles smaller than final segs/angles.  Segs/angles broken into congruent parts (usually double use of bisect/trisect/midpoint)

7. Division Property  Must have CONGRUENT PAIRS of segs/angles.  Given segs/angles larger than final segs/angles.  Segs/angles broken into congruent parts (usually double use of bisect/trisect/midpoint)

8. Proof Tips  Label given information on diagrams  Know ch. 1 and ch. 2 IF/THEN statements  When using comp/supp of congruent angles, make sure to show two pairs of comp. or supp angles!  Look for PAIRS of statements – comp/supp angles, mdpts, bisectors, trisectors  When using properties, make sure to show original segs/angles CONGRUENT!!!  If stuck, at least list all facts resulting from givens (and label on diagram).
