Hey.. i wanted to know that in a polygon, if 2 sides are equal, will the angles opposite to these be equal as well?
My Name can u help me out with dis?
Thats exactly what i was wondering about...hmmm in a regular polygon if all sides are equal all angles will be equal!! It might differ in irregular polygons!!
hey cross multiply
Why cross multiply? It have addition side in b/w and both have same denominatorhey cross multiply
If it's an irregular polygon, and you've got 2 equal sides, the angles are not necessarily equal. This is due to the fact that the other lines making those 2 angles may not be equal. Although, you can create an isosceles triangle this way by drawing a line, this creates 2 equal angles as the sides are equal. Or so I think.. It'd be better if I can draw you a diagram but Im currently out.Thats exactly what i was wondering about...
yeah that formula is right!! that is the formula to find out each interior angleIf it's an irregular polygon, and you've got 2 equal sides, the angles are not necessarily equal.

misscute406 Are you sure you have the right formula?
Why cross multiply? It have addition side in b/w and both have same denominator
like 4/2 + 4/2 = 8/2
You mean this formula is right: n(n-2)/180 ? Okay.yeah that formula is right!! that is the formula to find out each interior angle
sum of the first 'n' interior angle= n(n+1)/2View attachment 53328 Part (v)... help please
You mean this formula is right: n(n-2)/180 ? Okay.
Say I have 4 sides (quadrilateral), so n = 4,
4(4-2)/180 = 2 /45. But thats not right as each angle is 90..
The right formula is (n-2)*180 / n
First time heard it ... i really didn't knewOMG!! hey that is only for fractions which doesn't have an unknown!!These kind of fractions have an unknown x. If you don't cross multiply then you cannot find the unknown!!
My Pleasure!!First time heard it ... i really didn't knew
anyways thanks
yesHey.. i wanted to know that in a polygon, if 2 sides are equal, will the angles opposite to these be equal as well?
My Name can u help me out with dis?
can u give all pic of this paper plz [email protected]thanks! and btw can anyone help me with part 2 of this question https://fbcdn-sphotos-c-a.akamaihd...._=1439786632_c2ea98fc441ef3b7f225741d4352e9bb
well... y did u substitue (n-8) in the 1st place..Care to elaborate?sum of the first 'n' interior angle= n(n+1)/2
Step1: Substitute (n-8) in place of n
(n-8)(n-8+1)/2 = (n-8)(n-7)/2
Answer= (n-8)
The Chill Master ... can u help?View attachment 53328 Part (v)... help please

(n-8) is is substituted because it's at the position of n.Though I am not sure.The Chill Master ... can u help?
