Items 9-11: Use the diagram to the right to find the lengths of the segments given. ) 2 2 9.YZ= cm XY=2cm XZ-5cm M is the midpoint of XZ 10, XN cm 11, YM= cm

Solution

given XY=2, XZ=5

9)YZ

=XZ-ZY

=5-2

=3cm

YZ=3cm

10)M is the midpoint of XZ

XM=(1/2)XZ

XM=(1/2)(5)

XM=2.5cm

11)YM=XM-XY

YM=2.5-2

YM=0.5cm
