a/ Gọi x là số đo góc A tứ giác ABCD.(x>0)

Số đo góc B là x+20

Số đo góc C là 3x

Số đo góc D là 3x+20

Vì tổng số đo góc trong tứ giác là 360^onên ta có phương trình:

x+x+20+3x+3x+20=360

<=>8x = 320

<=> x=40(nhận)

Vậy góc A=40^O

  GÓC B=60^O

GÓC C=120^O

GÓC D = 140^O

B/ Ta có: góc A + góc D = 40^o+140^o=180^o

Mà 2 góc này ở vị trí trong cùng phía 

Nên AB//CD 

=> Tứ giác ABCD là hình thang
