Question

In the adjoining figure, ABCD is a
parallelogram in which LBAO = 35,
ZDAO = 40° and ZCOD = 105°
Calculate (i) ZABO, (ii) ZODC, (iii) ZACB
and (iv) ZCBD.​

Answer 1

Answer:

CBD =95

ODC = 40

ACB = 40

ABO = 40

Answer 2

Answer:

angle AOB=105

angleABO=180-105-35

=40°

angle ABO= angle ODC (alternate angle)

=40°

angle CAD= angle ACB(alternate angle)

=40°

angle ABC=180-75=105°

angle ABO=40

angle CBD=105-40=65°
