Question

9. The length of a line segment AB is of the length of the line segment CD. The length of
another line segment EF is of the length of the line segment AB. What fraction of the length
of CD is equal to the length of EF? If CD = 4 cm then find the length of EF.
​

Answer 1

Answer:

given : l of seg AB=l of seg CD

l of seg EF= l of seg AB

To Find :l of seg EF=?

solution : from the given condition,

we have the values,

AB=CD=EF.........(1)

means, these three lines are equal

therefore, if CD=4cm

then, AB=4cm

therefore, seg EF=4cm..........(AB=EF)......( by the property of transitivity)

therefore,

the ans. is

l of EF=4cm
