For Exercises 9 and 10, consider isosceles trapezoid RSTV with
a) Does
b) Does 

Exercises 9, 10
a)
To Explain:
Does
Consider the following isosceles trapezoid RSTV.
In an isosceles trapezoid,
Q is the midpoint of the side RV and N is the midpoint of the side ST.
QN is the median of the trapezoid RSTV.
We know that the length of the median (m) of a trapezoid is the average of the lengths of the bases.
It means
b)
