Suppose 12 points lie on a circle. How many cyclic quadrilaterals can be made by using these points? Choose one:
A) 440
B) 454
C) 495
D) 486
E) None
For any set of 4 points we get a cyclic quadrilateral. Number of ways of choosing 4 points out of 12 points is 12C4=495. Therefore, we can draw 495 quadrilaterals.   Answer 495
