Re: Acute angled circular
Raiyan speaking ,
I don't understand , if the points are A , B , C , D , E , F and G . Everyone says 14 or 28 are possible . But taking all types of triangle , we get 343 types . So , there might be much more types . Please try to think the ans carefully .

Re: Triangular problem
I actually mixed one with another . After I saw this question , although I knew the answer , to be sure I tipped it in the forum . But then I saw that it didn't have anything inside it . So , I posted it again . Also I don't think that I did do any change in it . Could you tell me what I changed ?
