ACTIVATOR 1. Rip your homework out and put your name on top. 2. Complete your pretest. You will have 15 minutes to complete. When you are done, flip it over and write down 2 things that you are interested in learning about in our Geometry unit.

OBJECTIVE(S): I will be able to: Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes. So that I can learn how to: apply these techniques in the context of solving real-world and mathematical problems. Find the area for a trapezoid by decomposing into two triangles. Decompose rectangles to determine the area of other quadrilaterals. I will demonstrate my understanding by verbally discussing and then writing the solutions to accurately solve at least 3 out of 5 real world problems. “break into pieces” “a 4-side shape” 6.G.A.1

Vocabulary: Triangle Quadrilateral Trapezoid Decompose Height Width Base Length half

Let’s look at it as a rectangle and taking away 2 triangles. We do #4 pg. 23 Let’s look at it as a rectangle and taking away 2 triangles. Rectangle: A=bh A= 18(12) A= 216 meters2 Triangle: A= ½ bh h=12 b= (18-3)/2 b= 7.5 A=1/2 (7.5)(12) A=6(7.5) A=45 meters2 but I have 2 triangles… Trapezoid: A=216-45-45 A=126 meters2
