Scribe Post, Mckenzie Chapter 5

Heyy!! Guys!! okay so today in class we started with Daily Quiz # 15

-Daily Quiz #15 was about finding the longest side and shortest side of a given triangle. For example: PQR, angle P has measure 50 and angle R has measure 60. Which side of the triangle (PQ, QR, or PR) is the longest side, and which has the shorter side?
-To solve this problem u had to use the rule: (pg. 42)
The Longest side of any triangle is always opposite the largest angle
The shortest side of any triangle is always opposite the smallest angle
- After this we went through our homework and started to go over chapter 5. we began to cover area and space. Jojo introduced some formulas on how to solve for Area with base(height). But here are all the formulas for all the different polygons: (pg 61, 63,66)
-Area of Square: A=S^2
-Area of a Rectangle: A=LW
-Area of a Parallelogram: A=bh
-Area of a Triangle: A=1/2 bh
-Area of a Trapezoid: A= 1/2h (b +b)
I just gave you guys gold please use it. New Scribe is Brandon :)
