INVESTIGATION 5

 

QUESTION:

The diagonals of a trapezoid divide the interior region into four nonoverlapping triangles. What is the relationship between the areas of the green triangles (the triangles that share a side with the legs)? What is the relationship between the areas of the yellow triangles (the triangles that share a side with the bases)? You may need to make additional measurements other than the area of the triangles. Explain your solutions.

 

 

MY SKETCH:

 

The area of the yellow triangles is about 1/2 the other.  The area of the green triangles are about the same.
