Which of the following lists the number of points at which a circle can intersect a triangle?
(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

Notice how the answer choices DIFFER.Which of the following lists the number of points at which a circle can intersect a triangle?
1. 2 and 6 only
2. 2, 4, and 6 only
3. 1, 2, 3, and 6 only
4. 1, 2, 3, 4, and 6 only
5. 1, 2, 3, 4, 5, and 6
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.
