Notes on Medians, Altitudes, Perpendicular Bisectors, and Angle Bisectors with their points of concurrency.

In this lesson students will begin with flash cards on example "statements" and "reasons" in a two-column proof. Students will then answer two questions as a class using half-filled two-column proofs, using problems they have solved before. Then, students will solve two problems without anything filled in about complementary and supplementary angles. Contains a link to the flashcards for online students also. www.mattedition.com

Notes are in word format, so they are editable! Contains options to review coordinate pairs, distance formula, and angles of a circle. Includes definitions of parallel and perpendicular lines with examples. www.mattedition.com

Assignment is meant to check student understanding of parallel and perpendicular lines. I used this worksheet the day after I taught the parallel/perpendicular lesson. Students see 13 slope-intercept equations of a line. They need to list which are parallel and perpendicular to three other lines. www.mattedition.com
