Topic 9 (Trapezoid Medians)

Today we worked with medians in trapezoids.

 

A median in a trapezoid is a line that connects the midpoints of the legs. The median is always parallel to the bases and its length is equal to the average of the lengths of two bases.

 

Follow this link and use the interactive animation to see that this is always true. http://www.mathopenref.com/trapezoidmedian.html

 

To see how we applied this fact to some algebraic problems check the classwork and the homework below:
