Question

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

Answer 1

Do you know what a regular polygon is?

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

:)

Answer 6

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

Answer 7

Can you plz explain more

Answer 8

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

Answer 9

i will draw to help

Answer 10

ur so much HELP @seldamat

Answer 11

Thanks for the help

Answer 12

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)

Answer 13

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
