How many diagonals does 11-sided convex polygon have?
How many diagonals does a polygon with 36 sides have ?
Công thức tính số đường chéo : \(\frac{n\left(n-3\right)}{2}\) trong đó n là số cạnh của đa giác.
Cách chứng minh ( tham khảo bên web khác ):
Tại đây. Từ đó đáp án là : \(\frac{36.33}{2}=594\)
Vậy ...Mn giải và dịch dùm bài này cái :
If the sum of al interior angles in a convex polygon is 1080 degrees, then this polygon has ........... diagonals.
tks mn
em chả hiểu gì cả, nhung đề bài đây
nếu tổng của tất cả các góc trong 1 đa giác lồi là 1080 độ . vậy đa giác có bao nhiêu đường chéo??????????
