1. ## Determining quadrants from pi

Im currently studying to take the ACT for the third time and am confused about how to figure out what quadrant different triangles will get zoned into based on pi. When looking up a missed question it says since pi/2 < x < pi; then x must be in quadrant II. Are there formulas like this for finding out all the quadrants? If so I would appreciate if someone could tell me about them. Thanks

In radians, $\displaystyle \pi$ corresponds to 180 degrees, so $\displaystyle 2\pi$ is 360 degrees. That should help you figure out how to write the four quadrants in terms of pi.
