Sides \($\overline{AH}$ and $\overline{CD}\)$ of regular octagon $ABCDEFGH$ are extended to meet at point $P$. What is the degree measure of angle $P$?

Hint: Try to use the formula 180*(n-2) / n to find the measure of one angle of the octagon. Then, go from there.


It's better to draw the diagram first!

Geometry questions are always a nightmare to write answers to, but I'll give it my best shot. If we connect CH, we get a right triangle. The interior angle of a regular octagon is 135 degrees (make sure you see why!). Therefore, with CH being perpendicular to GH, we know that angle AHC= 45 degrees. Therefore, angle P is I believe 45 degrees.

A little vague, so ask me if you need clarification.
