Coordinate Geometry: Locating Centers of Triangles

• 20 problems were on the board today
• whatever you did not finish in class is your homework
  

5.1 Bisectors of Triangles

• (9-29) odd


• (45)

5.2 Medians and Altitudes of Triangles

• (5-25) odd


• (35)


• (41)

Constructing the Orthocenters and Centroids of Triangles

Construct:

1. the orthocenter of an acute scalene triangle


2. the orthocenter of an obtuse triangle


3. the orthocenter of a right triangle


4. the centroid of acute scalene triangle


5. the centroid of of an obtuse triangle


6. the centroid of a right triangle


7. circumscribe a circle about an acute triangle


8. circusmscribe a circle about an obtuse triangle


9. inscribe a circle in an acute triangle (remember, you MUST construct a perpendicular from the incenter to any side (preferably the longest side) of a triangle first BEFORE you can inscribe a circle!!!!)


10. inscribe a circle in an obtuse triangle

Constructing the Circumcenters and Incenters of different types of triangles

Construct the:

1. circumcenter of an acute triangle


2. circumcenter of an obtuse triangle


3. circumcenter of a right triangle


4. incenter of an acute triangle


5. incenter of an obtuse triangle


6. incenter of a right triangle

if you are even the tiniest bit off, do it over again!!!!!! PERFECTION is what you are striving for in a construction!!!!

please use colored pencils and/or highlighters to help you identify the different perpendicular bisectors and angle bisectors in your constructions. no color = no bueno =(

retry proofs in sections 4.4-4.6

• since we did sooooooooooooooooo many proofs in class today, i wanted to give you guys another opportunity to showcase your intelligence so try doing the other even proofs that i did not discuss in class today. if you still can't figure it out, i will go over them tomorrow

Constructions

• at this point, everyone should know how to:


• copy a segment


• copy an angle


• construct an isosceles triangle


• construct an equilateral triangle


• construct a 60 degree angle


• if you don't know how to do any one of these, google it, youtube it, something.... there are videos out there. i've seen them


• 2 new constructionS alert!!!! (pg. 231)


• KNOW how to construct the perpendicular bisector of a segment and the angle bisector as we will be using these techniques to discover our next theorems tomorrow in class.

4.5 ASA and AAS

• (7-19) odd

4.6 Isosceles and Equilateral Triangles

• (9-23) odd

• (1-28) all
• have a PG-13 weekend!
• and if you want to get a head start on the next lesson, you can read up on 4.5 and 4.6 (hint hint)
  

4.4 SSS and SAS shortcuts to proving that triangles are congruent

• (6-28) even


• no HW Wed. or Thurs.


• I know....you guys are shocked


• enjoy the 2 days off because....


• you will HAVE HW Friday for the weekend


• so....check back here Fri.


• be good


• toodles!


• love you guys!

4.3 Congruent Triangles

• (9-29) odd

4.4 SSS and SAS Congruence

• (5-29) odd

Constructions

• copy the directions on pgs 264 and 265


• then PRACTICE following these steps!
