ii.In figure, points X, Y, Z are the midpoints of side AB side BC and side AC ofangle ABC respectively. AB = 5cm , AC= 9cm and BC = 11 cm. Find the lengthof XY, YZ, XZ. About the author Vivian
Answer: Given that X,Y and Z are the midpoints of the side AB,BC and CA respectively. By midpoint theorem XZ∣∣BC and XZ = 2 1 BC BC=11cm ⇒XZ= 2 BC = 2 11 =5.5cm Similarly, XY∣∣AC and XY = 2 1 AC AC=9cm XY= 2 AC = 2 9 =4.5 cm YZ∣∣AB and YZ = 2 1 AB AB=5cm YZ= 2 AB = 2 5 =2.5 cm Reply
Answer:
Given that X,Y and Z are the midpoints of the side AB,BC and CA respectively.
By midpoint theorem
XZ∣∣BC and XZ =
2
1
BC
BC=11cm
⇒XZ=
2
BC
=

11
=5.5cm
Similarly,
XY∣∣AC and XY =

1
AC
AC=9cm
XY=
2
AC
=

9
=4.5 cm
YZ∣∣AB and YZ =

AB
AB=5cm
YZ=
