STUDY GUIDE FOR CP GEOMETRY QUARTER 2 EXAM NOTE: The exercises in this study guide do not represent the entire scope of the quarterly exam, rather it is a sampling of vocabulary and practice problems to help you study. In order to fully prepare for the exam, it is recommended that you review all returned quizzes and tests, all class notes, and all homework problems. ITEMS TO REVIEW: Congruence Statements and Corresponding Parts Triangle Congruence Postulates: Side-Side-Side Side-Angle-Side Angle-Side-Angle Angle-Angle-Side Hypotenuse-Leg CPCTC How to develop a two-column proof Perpendicular Bisector Theorem Angle Bisector Theorem Triangle Sum Theorem Triangle Inequality Theorem Hinge Theorem Relationship of sides to the opposite interior angles in a triangle Segments drawn in triangles: Midsegment Medians Altitudes Perpendicular Bisectors Angle Bisectors Points of Concurrency: Centroid Incenter Circumcenter Orthocenter Characteristics of POC: Which is the center of gravity? Which is equidistant from each vertex? Which is equidistant from each side? Which divides each median into a 2-to-1 ratio? PRACTICE EXERCISES 1. Solve for x. 2. Find the possible values for x in the triangle. 3. What is AN? 4. What is the value of x? 5x-9 2x (2x+5)° (3x-1)° 5. If two sides of a triangle are 20cm and 24cm, what are the possible lengths of the 3rd side? 6. Name six pairs of corresponding parts if ∆PIG ∆CAT. 7. Identify the centroid, circumcenter, incenter, and orthocenter of the triangle shown. Given: KJ MN; Prove: JL NL Statements KJL MNL K M L Reasons J N
