Given:

AB= 20, BV=12, VA=14 and SR is a mid segment.

To find:

The lengths of SR and AR.

Solution:

SR is a mid segment. So, SR is parallel to the non-included side BV and the length of SR is half of BV.


SR=(1)/(2)BV


SR=(1)/(2)(12)


SR=6

SR is a mid segment. So, it divides the included sides in two equal parts. It means R is the midpoint of VA.


AR=(1)/(2)VA


AR=(1)/(2)(14)


AR=7

Therefore, the measure of SR is 6 units and the measure of AR is 7 units.
