what is two and three dimensional figure?how to find faces,vertices,edges etc of the shape?
A two-dimensional figure is formed by set of line segments (sides) or curves. It lies completes on a flat surface.
The sides are called edges of the figure.
The end points of edges are called the vertices.
Quadrilaterals, circles, etc are all two-dimensional figures.
A three-dimensional figure is an object having height, width or depth,
Its flat surfaces are called faces of the object.
Cube, cuboid, Cone, cylinder, etc are all three-dimensional figure.
