1. Ch. 1 Review Honors Geometry

2. Test Topics (sections 1.1-1.5)  Naming geometric figures  Union/intersection  Degree conversions  Congruence  Writing/Solving Equations  Clock problems  Assumptions (straight angles)  Basic 1 Step Proofs (if/then statements)

3. Test Topics  Basic 2 col proofs (be able to fill in steps)  Bisectors/Trisectors/Midpoints  Ratio Problems  Converse/Inverse/Contrapositive

4. Test Reminders  Bring notebook for notebook check!  Bring a calculator  Have review completed  Test is 25% of grade – no retakes!  Make sure you prepare to finish in 50 min  If then statements must match given info!

5. Clock Problems  Calculate the measure of the angle created by the hands of a clock at 2:50. 145 Degrees

6. Ratio Problems  If a 15 cm segment is divided in a 2:3 ratio, how long is the smaller segment?  6 cm  If a right angle is divided in a 4:5 ratio, how large is the larger angle?  50 degrees

7. Intersection/Union

9. One-Step Proofs If an angle is bisected, then it is divided into two congruent angles.

10. One-Step Proof If a point divides a segment into two congruent segments, then it is a midpoint.

11. One-Step Proof If angles are right angles, then they are congruent.

12. One-Step Proof If segments have the same measure, then they are congruent.

13. Logic Statements “If you live in Cincinnati, then you live in Ohio.” Converse: Inverse: Contrapositive: (Is each statement true or false?)

14. Logic Statements “If you live in Cincinnati, then you live in Ohio.” Converse (False): “If you live in Ohio, then you live in Cincinnati.” Inverse (False): “If you do not live in Cincinnati, then you do not live in Ohio.” Contrapositive (True): “If you do not live in Ohio, then you do not live in Cincinnati.”
