There are 12 points in a plane of which 5 are collinear. Except these five points no three are collinear, then

Options

A. The number of quadrilaterals one can form using these points is 420
B. the number of Deltas one can form using these points is 210
C. the number of lines one can form using these points is 57
D. the number of lines one can form using these points is 56

Answer

A, B, C

Explanation

(A) .^(12)C_(4)-(` .^(5)C_(4)+^(5)C_(3).^(7)C_(1))=495-(5+70)=420`
(B). .^(12)C_(3)-(` .^(5)C_(3))=220-10=210`
(C). .^(12)C_(2)-(` .^(5)C_(2))+1=66-10+1=57`
