`ABCD` is a quadrilateral with `/_A = 80^@, /_B = 40^@, /_C = 140^@, /_D = 100^@`. (i) Is `ABCD` a trapezium? (ii) Is `ABCD` a parallelogram?

ABCD is a quadrilateral, then /_A+/_B+/_C+/_D=

ABCD is a cyclic quadrilateral in which /_DBC = 80^@ and /_BAC = 40^@ . Find /_BCD .

(True/ False) ABCD is a cyclic quadrilateral such that /_A = 90^@ , /_B = 70^2 , /_C = 95^@ and /_D = 105^2 .

ABCD is a quadrilateral in which /_A= 60^(@), /_ B= 70^(@), /_ C =110^(@) and /_ D =120^(@) . The number of pairs of parallel lines is "________________" .

In quadrilateral ABCD, /_A+/_B= 150^(@) Then /_C+/_D= …….

In the figure,ABCD is a cyclic quadrilateral. Also /_A+ /_D = 120^@, /_D + /_C= 250^@ .What is /_A+/_C

ABCD is a parallelogram in which /_A=70^(@) Compute /_B,/_C and /_D

ABCD is a parallelogram in which /_A=70^(@) Compute /_B,/_C and /_D.
