    Measure of an internal angle

    How would I find the measure of an internal angle of a regular n-gon?

    Anyone remember the formula? I think it is something like:

    180n
    n-2

    almost; 180 * (n-2)/n
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

    n

    ?

    Cool.

    By the way, I went to your site (you have a link to it in your signature). You have a link to a site about Turku. Do you happen to be from/living there?

    Joo, minä asustelen tällä hetkellä jenkeissä mutta en ole tänne tullut jäädäkseni. Sitäpaitsi täällä on koko ajan liian hyvät kelit suomalaiseen makuun ... Faijaa pyydettiin lähtemään soneran maailmanvalloitukselle, mietittiin vähän aikaa ja päätettiin lähteä. Onhan täälä ihan rentoo. Ja pikaruokaa on paljon enempää sorttia .

    Törmäsin tässä juuri vähän aikaa sitten pariin toiseenkin suomalaiseen. MerryVIP on, ja se sanoi jostain Kajemanista että sekin olisi (ellei tarkoittanut sinua)...

    What angle are you talking about?

    Maybe I do not understand what angle you are talking about.

    Shouldn't you get 90 degrees for a 4-gon (square), and 60 degrees for a 3-gon (triangle)?

    180 - 360 / n looks like a good formula to me.

    For the central angle of a Pie-shaped slice: 360 / n
