Perimeter and Area of Triangles With Coordinates
Bellringer Part 1: Find the area of the shaded region. Explain your reasoning.
Bellringer Part 2: Find the area of the shaded region. Explain your reasoning.
Use the applet below to find the area of a triangle using the decomposition method. You will enter your answers in the question boxes that follow. (You will do this for 3 triangles).
Triangle 1
Once you correctly find the area of a given triangle in the above applet, explain how you found your answer here. Sample Answer: "Area of the rectangle = 24, then subtract the area of the outside triangles. 24 - 5 - 3 = 16."
Triangle 2
Once you correctly find the area of a given triangle in the above applet, explain how you found your answer here
Triangle 3
Once you correctly find the area of a given triangle in the above applet, explain how you found your answer here
