2008-2009 practice math question

<p>You guys remember that question with blocks and m and the firehouse? I still dont understand question 18. m distance of 3 must lie on a square? I dont understand this one. Anyone remember it and how to do it?</p>

<p>ya wanna sorta…you know, type out the actual question?</p>

<p>yeah, its a circle, radius of 3, infinitely many points,u connect them,becomes a circle</p>

<p>huang- i dont think typing will help but just for you. </p>

<p>All of the buildings in the town that are m distance of 3 from the firehouse must lie on a </p>

<p>A. Circle
B. Square
C. Right Isosceles Triangle
D. Pair of Intersecting Lines
E. Line</p>

<p>Ren- the answer isnt circle though</p>

<p>oh then its a square since u cannot go diagonal~~ lol the Q says that we have to follow the lines right? so connect the dots … its a square</p>

<p>and im answering this by memory lol…</p>

<p>Yeah, I remember this one. A circle would go THROUGH the houses. Since you can only use the road (which is in the form of a square grid), the figure that you obtain is a square. ;)</p>

<p>In case Ren and uttaresh sound too cryptic:
Since the buildings can be located in the grid knots only, mark the grid knots that are three unit segments route<a href=“this%20route%20does%20not%20have%20to%20be%20a%20straight%20line”>/u</a> away from the firehouse.
“connect the dots”.</p>
