In the given figure, `AB"||"CD and O` is the midpoint of AD.
Show that (i) `DeltaAOB~=DeltaDOC.`
(ii) O is the midpoint of BC.

In the given figure.AB|CD and O is the midpoint of AD.

Line-segment AB is parallel to another line-segment CD. O is the mid-point of AD (see Fig. 7.15). Show that (i) DeltaA O B~=DeltaD O C (ii) O is also the mid-point of BC

In the figure AB || CD, AD and BC intersect at o and O is mid-point of AD. Show that (i) DeltaAOB~=DeltaDOC and (ii) OB=OC .

In Figure,line segment AB is parallel to another line segment CD.O is the mid-point of AD. Show that: (i) AOB~=DOC( ii) O is also the mid-point of BC.

In given figure,show that AB|CD

In the given figure, AB and DC are both perpendicular to line segment AD. BC intersects AD at P and P is the midpoint of AD. Prove that, ( 1 ) AB = CD ( 2 ) P is the midpoint of BC.

Line segment AB is parallel to another line segment CD. O is the midpoint of AD (see the given figure). Show that (i) triangleAOB = triangle DOC (ii) O is also the midpoint of BC

In the given figure, OA = OB and OD = OC. Show that (i) DeltaAOD cong DeltaBOC and (ii) AD||BC

In quadrilateral ABCD, AB||CD and BC||AD. Show that (i) DeltaABD~=DeltaCDB

In Figure,if AD is the bisector of LA, show that: AB>BD( ii) AC>CD
