What is the difference between a convex shape and a concave shape?
i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.
What is the difference between convex polygon and non convex polygon?
A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.
How many vertices are in a 3d rectangle?
Rectangles are 2-dimensional figures- they lie in a plane- they have four vertices There really is no such thing as a 3D rectangle. If you mean a rectangular prism, it has 8 vertices, 4 on each of its two parallel faces.
