-11/2: -3.2 Go over setting a notebook. Keep a part for Conjectures. As a class construct a perpendicular bisector.
Assignment: 1-10, 13 and 14
3.3: Investigation 3.3.1...do C-3 Assignment: 1-3, 5-6
-11/4: Go over questions from Homework, in pairs have students complete constructions we have done so far in this chapter
3.4: Investigation 3.4.2 and Investigation 3.4.3 Assignment: 1-12, for problems 6-12, actually construct the angles
11/9: Go over homework, then start investigation 3.5.1, Assignment 3.5: 6, 9, 11
11/13: Go over homework from 3.4 and 3.5, then do worksheet 3.5.
11/19: 3.6: 1-5
11/30: Investigation 3.7, 3 points of concurrency!
Incenter: 3 angle bisectors in a triangle
Circumcenter: 3 perpendicular bisectors of a triangle
Orthocenter: 3 altitudes of a triangle
Circumscribe: Circle passes through each vertex of a triangle (use circumcenter)
Inscribe: Circle within the triangle touching each side (use incenter)
-hand out triangle sheets and find the incenter, circumcenter
12/2: Orthocenter and Centroid.
Centroid= 3 medians...construct on final sheet of triangles
-complete investigation 3.8.2 and answer C-12
12/4: 3.8 1-4, then start sheet 3.8
12/7: finish 3.8 sheet
12/9: the constructions final packet!
-Modified 3.8.3: Make a large triangle on a piece of cardboard. Construct all points of concurrency on this triangle, answer c-13 and c-14.
Euler line: orthocenter, centroid, and circumcenter are all on a line
https://www.geogebra.org/m/21244
-significance of the euler line: http://faculty.evansville.edu/ck6/tcenters/class/eulerline.html
After packet: Cut out the triangle and balance it on a pencil, is the centroid the center of gravity?
-When done....Watch Fractals video
12/14: 4.1: do investigations 4.1.1 and 4.1.2 as group. Record c-15 and c-16.
4.1: 1-5, 7-8, 10-11
12/16: 4.2: Lecture on parallel line props. Do c-17 as a group.
4.2: 1-7, Photocopy 9, 18-20
Move on to chapter 5....come back to the chapter 4 stuff
5.1: Complete investigation 5.1.1, complete C-25 and C-26
1-9
