#### number of points a circle can intersect a triangle

Tue Feb 22, 2011 8:03 pm
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

How do you solve? I don't even understand this question.

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

The Official Guide doesn't have a formal definition of "intersect," but we can infer its meaning from the test-maker's definition of a closed plane figure (e.g., a rectangle):

A polygon is a closed plane figure formed by three or more line segments, called the sides of the
polygon. Each side intersects exactly two other sides at their endpoints.

So, the adjacent sides of a rectangle do not pass through each other, but they are said to intersect.

Cheers,
Brent

How do you solve? I don't even understand this question.
The quickest approach is to notice how the answer choices differ. Only answer choice E says that 5 intersections are possible:

Since 5 intersections are possible, eliminate A, B, C and D. No need to try any other options.

@GMATGuruNY,

I beg to differ. For those who don't even understand the question (like me!) Your explanation doesn't help at all. What if the testmakers purposely threw in the 5 to confuse those who don't know what to do? I'll appreciate if you could give a more detailed explanation. Thank you!
