    (a) 2 and 6 only
    (b) 2, 4, and 6 only
    (c) 1, 2, 3, and 6 only
    (d) 1, 2, 3, 4, and 6 only
    (e) 1, 2, 3, 4, 5, and 6

    Answer: E

    The important takeaway here is that "intersect" does not necessarily mean "pass through"
    So, a line that is tangent to a circle (touching the circle but not passing through it) can be said to intersect the circle. To intersect is to share a common point.

    Cheers,
    Brent

    5. 1, 2, 3, 4, 5, and 6
    Notice how the answer choices DIFFER.
    Only E states that the circle and the triangle can intersect at 5 points.
    If it's possible for there to be 5 intersections, A, B, C and D can be eliminated.



    Since 5 intersections are possible, eliminate A, B, C and D.

    The correct answer is E.
