Thread: Trapezoids

This question says Let JK be the median of ABTQ and find JK.

here is the picture to go by attached!!!

Is AB the Median of QRST?

yes AB is the median for QRST

That was a thought question.

What is the length of AB and how did you determine it?

AB is the median of trapezoid QRST.

The length of the median of a trapezoid is one-half the sum of the lengths of the two bases.



Substitute known values for RS and QT and solve for AB.

Since JK is a median of trapezoid ABTQ,



All variables except JK should be known at this point, so substitute values for AB and QT and find JK.
