You can get the angles of a regular polygon no matter what by dividing the number of sides by 360. Also exterior + interior angle does not always = 180 degrees. In the case you are showing it it is, but the exterior angle in other examples is not always straight through.
@Flaky80 for the exterior angles yes but think of a triangle 3 sides 360/3=120 but we know that each angle is 60 interior + exterior=180 i dont where you got that it isnt from most textbooks have this rule as far as i know and also note the problems are NOT drawn to sacle a lot of the time so it may look like that but it has to carry out in a staright line
yes i would hope so if i am teaching it just say things wrong sometimes i panic a bit too fitting them into the 10 min time limit its a bit short really for teaching
no problem it is tricky at first until you see the idea most teachers use formula first but i like to first use triangles i think it gives people a good idea but formula as well good have a choice of methods
thank u so much 4 helping, may i ask, a pentagon has 5 sides right? so if we divide it we will get 3 triangles? so that's why all the sides of a pentagon adds up to 540 degrees coz 180 times 3?? is it right? thanks again!
Thank you sooo much fella this helped alot.

yeah there are 3 triangles in a pentagon and each is 180 degrees times by 3 540 yeah thats rightyou have got the idea glad it helped
