If it is a closed figure which doesn't cross over itself (like a bowtie looking figure), then it is called a polygon.
A sphere
Yes, a two-dimensional figure is typically defined as a shape that is enclosed by lines, which can include straight lines, curves, or a combination of both. Examples of two-dimensional figures include squares, circles, triangles, and rectangles. These shapes occupy a flat plane and have both length and width but no depth.
a cirsquare
They are all polygons: two-dimensional shapes, bounded by straight lines.
no it is a 4 dimensional figure not a 3 dimensional figure * * * * * No. A quadrilateral is a two dimensional figure. It has a length and a breadth and no more.
A sphere
Yes. A polygon is any closed two dimensional figure made of straight lines. It is also a irregular polygon.
a cirsquare
A cylinder.
There are two two-dimensional figure with an infinite length. They are rays, and lines.
Lines! Yes, they are one-dimensional. Points are zero dimensional, planes are two-dimensional, and prisms and such are three dimensional.
The intersection of two lines is a point. If both lines are straight the figure of four separate triangles are formed. The type of triangles are dependent on the angle of the intersection.
Perpendicular lines or parallel lines are two examples
Three straight sides Closed figure two dimensional three angles
It's an irregular polygon
yes - one criterion of a polygon is being made up of only straight lines. polygons are also 2-dimensional. a cylinder is neither of these two things, as it is 3-dimensional (has length, width, and depth) and its two bases are circles, which are curved.
