    Question help (from cambridge 3 unit year 11)

    Hi,

    I came a cross a question from exercise 8D and i'm utterly confused.

    7. a) If ABCD is a parallelogram, show that SinA = SinB = SinC = SinD.

    It said that it is related to trigonometry and incorporated trigonometric work. Does it involve the supplement of the parallelogram or have anything to do with the sin angle?

    Please help
