Math question help!!!

<p>If someone could help me with these two math questions that would be GREAT!!! I seem to have trouble with these spacial type questions....</p>

<p>If three different circles are drawn on a piece of paper, at most how many points can be common to all three?
a) none b) one c) two d) three e) six</p>

<p>Three lines are drawn in a plane so that there are exactly three different intersection points. Into how many nonoverlapping regions do these lines divide the plane?
a) three b) four c) five d) six e) seven</p>

<p>Thanks!!!</p>

<p>How many outscribed circles can a hexagon have?
A triangle?
How many different circles can pass through two points?</p>

<p>=================
Extend each side of a triangle.</p>

<p>Three lines are drawn in a plane so that there are exactly three different intersection points. Into how many nonoverlapping regions do these lines divide the plane?
a) three b) four c) five d) six e) seven</p>

<p>Answer: Seven</p>

<p>Draw a square as the representation of a plane, the lines will enclose a triangle. So you will get 7 planes.</p>

<p>How many different circles can pass through two points?
Infinite</p>
