Best ResponseYou've already chosen the best response.0Do they look vertically opposite to you?

Best ResponseYou've already chosen the best response.0Yes, so that's probably false. Maybe the angles are a linear pair?

Best ResponseYou've already chosen the best response.1Look up the definition of vertical angles. http://www.mathsisfun.com/geometry/verticalangles.html

Best ResponseYou've already chosen the best response.0Degrees, that is. \[\angle OSN = 90\]

Best ResponseYou've already chosen the best response.1there is no way to know the actual degrees in this diagram with no given angle information. However, we can state if the angles are vertical or not.

Best ResponseYou've already chosen the best response.0So, the angles are a linear pair? Both supplementary and adjacent.

Best ResponseYou've already chosen the best response.1LSM and OSN are vertical angles, they are equal.

Best ResponseYou've already chosen the best response.0But vertical angles are congruent. Horizontally, LSO and MNS are congruent, but not vertically.

Best ResponseYou've already chosen the best response.0It's still odd how each angle equals 180 and 90 degrees. Why wouldn't they be a linear pair? If I center the protractor on S, then each angle can be identified as 145 + 35 and 90 degrees.

Best ResponseYou've already chosen the best response.1the adjacent angles are supplemental so i understand where you are getting the 180 but am unsure of where your 90 degrees is coming from...

Best ResponseYou've already chosen the best response.0It doesn't matter if the angle is smaller? The top and the bottom just don't seem that equal to eachother.

Best ResponseYou've already chosen the best response.1Top angle would be <LSM and bottom angle would be <OSN

Best ResponseYou've already chosen the best response.1i think that the fact that the quadrilateral is irregular is throwing you off about the angles. With your protractor you should be able to prove that <LSM = <OSN and that <LSO = <MSN

Best ResponseYou've already chosen the best response.0I think so. Wow, what a problem. Thank you very much. :)
