Question

ABCD is a quadrilateral with angle ais aqual to 80 degree angle b is equal to 40 degree angle c is equal to 140 degree angle d is equal to 100 degree is ABCD is Trapezium​

Answer 1

A=80 b=40 c=140 d=100

80+40+140+100=360 we know sum of angles of trapezium is 360

and a+b+c+d=360

so abcd is a trapezium
