    and AC = 20 cm. The number of circles passing through points A,B,C is:
    A 2 Correct Answer Incorrect Answer
    C 1 Correct Answer Incorrect Answer
    D 3 Correct Answer Incorrect Answer

    Solution

    A, B, C three points. AB = 9 cm BC = 11 cm AC = 20 cm Property of formation of triangle is; Sum of any two sides must be greater than the 3rd side. i.e. a + b > c where a, b, c are three sides of the triangle. ∵ AB + BC = AC ∴ No triangle can be formed using the three sides given. ∴ No circle will pass through the points A, B, C.
