Question

plz solve this......​

Answer 1

ANSWER:

given,

BC=DA . and CD and AB intersect at point O

EXPLANATION

Make the 2 triangles congruent.

since, BC=DA (given)

angle COB=DOA (vertical opposite angle)

angle BCO=ADO(alternative angles)

hence, 2 triangles are congruent by SAS rule

and since these are congruent

hence, AO=BO

CO=DO

and as we know that adding equal amounts is equal so,

AO+OB=AB

CO+DO=CD

hence, AB=CD

hence, O is the mid point of AB and CD as they intersect.
