Can I find x and y coordinates for the vertices of an octagon with sides of unequal lengths and angles?

Knowing only the lengths of the sides, which are: 4.283, 4.227, 4.259, 4.259, 4.226, 4.246, 4.251, 4.248, can I find the x and y points of the vertices to within three decimal places? If so, how? I have a grade 10 level understanding of math.
After reading the replies, I can see how knowing only the lengths of the sides isn't enough. What if I knew the distances across opposite vertices?

No. You can't determine the shape of an octagon from the lengths of its sides. You can't even determine the shape of a quadrilateral from the lengths of its sides. You need more data.

No. Basically for any polygon with four or more sides, you can squish it and move the vertices. Triangles are rigid, as shown by side-side-side.

Of course! I would need angles.
