ABCD is a trapezium in which AB || DC and E is the mid-point of AD. If F be a point on BC such that EF || DC, then prove that `EF=1/2(AB+DC).`

ABCD is a trapezium in which AB||DC and let E be the mid point of AD. Let F be a point on BC such that EF||AB. Prove that EF=1/2(AB+DC)

ABCD is a trapezium in which AB||DC and let E be the mid point of AD. Let F be a point on BC such that EF||AB. Prove that F is mid point of BC.

Let ABCD be a trapezium in which AB||DC and E be the mid-point of AD. If F be a point on BC such that EF||AB. Then EF, where F is the mid-point of BC, is equal to

In the given figure. ABCD is a trapezium in which AB|| DC and E is the mid-point of AD, if EF||DC, then show that EF=(1)/(2)(AB+DC) .

In the given figure. ABCD is a trapezium in which AB|| DC and E is the mid-point of AD, if EF||DC, then show that EF=(1)/(2)(AB+DC) .

ABCD is a trapezium, in which AD||BC, E and F are the mid-points of AB and CD respectively, then EF is:

In Figure,ABCD isa trapezium in which side AB is a parallel to side DC and E is the mid- point of side AD. If F is a point on the side BC such that the segment EF is paralle side DC. Prove that F is the mid point of BC and EF=(1)/(2)(AB+DC)

In the figure ABCD is a trapezium in which side AB is parallel to side DC and E is the midpoint of side AD.If F is a point on the side BC such that the line segment EF is parallel to DC.Prove that Fis the mid-point of B BC and EF=(1)/(2)(AB+DC)

In Fig. , ABCD is a trapezium in which AB || DC and P, Q are mid-points of AD and BC respectively. If CP and BA when produced meet at E, prove that PQ=1/2(AB+DC) .
