Q2 of 12 Page 19

In the figure alongside, line a|| line b|| line c. Line d and line e are their transversals and intersect them in points P, Q, R and L, M, N respectively. Point Q is the midpoint of seg PR. If l(QR) = 7.2 and l(LM) = 6.2, find l(PQ) and l(MN).

From the figure we can say that the lines a, b, c parallel to each other and they are equidistance to each other.


So, length of segment PQ and length of segment QR


∴ l(PQ) = l(QR)


∴ l(PQ) =7.2 cm


Similarly, l(LM) = l(MN)


6.2 = l(MN)


∴ l(MN) = 6.2 cm.
