Find the number of sides of a regular polygon if one interior angle is 120 degrees. 3 4 5 6

Do you know what a regular polygon is?

If I think it is what it is, then two of the angles have to be 120 right? So 120x2 = 240, that leaves 120

that means 3 sides do you follow my logic (i hope you are actually learning and not using this to finish last minute hw)

A polygon with all the angles equal and all the sides equal.

:)

ok so im kind of under stand n what you are say n

Can you plz explain more

yup, so 360/120 = 3, 360 degrees and you must have 120 angles so divide 360 by 120 and you get how many times you can have 120 degree angle given a 360 degree constraint

i will draw to help

ur so much HELP @seldamat

Thanks for the help

crappy drawing - but you know that you have one angle that is 120, and that all angles must add up to 360. (i drew it wrong)

You also know that all the angles are equal, so you can divide 360, by 120 to know how many times you can have 120 degree angles given a max of 360 total degrees

hey can you help with my next ?

im just hanging out till someone helps me with my prob :\

i can try
