GRADE LEVEL: HIGH SCHOOL GRADING PERIOD: QUARTER 2 CONTENT STANDARD INDICATORS LOGIC AND PROOFS G.LP.4: Develop geometric proofs,  Proofs including direct proofs, indirect proofs, proofs by contradiction and proofs involving coordinate geometry, using two‐column, paragraphs, and flow charts formats. G.PL.4: Know that parallel lines have  Slope  Equations of lines the same slope and perpendicular lines have opposite reciprocal slopes. Determine if a pair of lines are parallel, perpendicular, or neither by comparing the slopes in coordinate graphs and in equations. Find the equation of a line, passing through a given point, that is parallel or perpendicular to a given line. SUBJECT: GEOMETRY MASTER COPY 10‐8‐15 DATE: 2015‐2016 SKILLS ASSESSMENT VOCABULARY 
