Question

Please do question 10

Answer 1

Answer:

Step-by-step explanation:

Proof

Because that CB is produced to E, and DA//CB,BE=CB

So BE//DA,DA=BE

So DB//AE

So AEBD is a parallelogram

Answer 2

Answer:

AEBD is a parallelogram

Step-by-step explanation:

It is given that ABCD is a parallelogram

Then AB || CD , BC || AD, AD = BC and AB = CD

And also, CB is produced E, Such that BC = BE

To prove AD || BE and AD = BE

from the given data,

BE || AD (Since BC || AD)

BE = AD (Since BC = AD)

For a quadrilateral if one set of opposite sides are equal and parallel then the quadrilateral is parallelogram.

Therefore AEBD is a parallelogram
