Question

11.Given a parallelogram ABCD . Complete each statement along with the definition

or property used.


i. AD =-----------

ii. BCD = ------------

iii. OB = ------------

iv. m <ABC+ m <BCD​

Answer 1

Answer:

AD=BC(opposite sides of llgm are equal )

BCD=BAD or DAB(opposite angle of llgm are equal )

OB=OC(O divides diagonal BC into two equal parts )

180 degree sum of adjacent angles of llgm is 180 degree

pls mark as breanliest or follow me if it is helpful

Answer 2

Answer:

I. AD=BC

2.BCD=BAD

3.OB=OD

Step-by-step explanation:

1.opposite sides of a parallelogram are equal.

2. opposite angles of a parallelogram are equal

3.(As the figure wasn't given I assume that O is the point of intersection of the diagonals) Diagonals in a parallelogram bisect each other.
