Circle can intersect a triangle.

[its.ur.life]

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

1. 2 & 6 only
2. 2,4 & 6 only
3. 1,2,3 & 6 only
4. 1,2,3,4 & 6 only
5. 1,2,3,4,5 & 6 only.

Ans is 5

Kindly explain as to what is asked in the ques and how to solve it.

draw a circle, and draw a triangle. do they intersect? if so, at how many points? for what it's worth, the correct answer is not here, so i know the problem has not been transcribed correctly from a GMAT Prep test. can you give us a screenshot so we can see what the question and answers really looked like?

This is actually the correct formulation of the question and the GMAT Prep provide "1,2,3,4,5 & 6" as the correct answer. Therefore, I understand that when a vertices of the triangle touch the circle it is interpreted as intersecting. Otherwise, I don't understand.

"intersect(ion)" means "points that are in both figures". so, yes, these would be points of intersection.

but now i'm confused—how else would 'intersection' be defined?
