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

Includes: - descriptions of each congruence - Why ASS and AAA do not work - 17 Questions of easy/medium difficulty to get students started with the material

I recommend this activity after going over all vocabulary. I noticed students were either forgetful or did not understand some so I created this activity. In this activity, students will measure angles and sides to find all parts of a triangle. They will use strips of paper to mark medians, altitudes, etc for the teacher to walk around and see if they are placing the strips correctly. In preparation for this activity: -Print out the three triangles (the next three slides). I made them fill up t

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

See attached worksheet. I created videos for all of the odd questions. The assignment was assigned to students for homework. I recommend instructing them to do the even questions with the odd solutions as a guide.

In this lesson, I review reflection and translation and give me an intro to Rotation. worksheet is meant to work through assignment with students.

Here is a lesson plan I used to teach students about triangle angle sums. I proved to them that the three angles are supplementary. Then we did practice problems, which are linked in the lesson plan with video solutions for 1-15 odd. More resources here.

contains education research, slope lesson plan, Kahoot review, and a great Physics Education resource. www.mattedition.com
