Question

In a rhombus ABCd ifangle a=60find angle band d

Answer 1

a rhombus is a type of parallelogram with its opposite sides equal

so angle a + angle b = 180degree

(co int. angle)

60 degree + angle b= 180 degree

angle b = 180 degree - 60 degree

angle b= 120 degree

angle b= angle d ( opp. angle of parallelogram)

120degree = angle d
