Welcome to the AoPS Wiki!

The AoPS Wiki project is administered by the Art of Problem Solving for supporting educational content useful to avid math students.

During AMC 10/12 testing week, the AoPS Wiki is in read-only mode. No edits can be made.

Problem of the Week

2008 AMC 10B, Problem 14

Triangle $OAB$ has $O=(0,0)$, $B=(5,0)$, and $A$ in the first quadrant. In addition, $\angle ABO=90^\circ$ and $\angle AOB=30^\circ$. Suppose that $OA$ is rotated $90^\circ$ counterclockwise about $O$. What are the coordinates of the image of $A$?

New to the AoPS Wiki?

If you don't know much about how to edit a wiki, you might want to read the tutorial and the help files. You can also read what AoPSWiki is not. Lastly, please read the policies of the AoPSWiki before editing, and why AoPSWiki is different from other online resources.

AoPSWiki runs on the MediaWiki software.
