Okay, you know those big mirror like things that they have in hospitals on stores to see whats coming around the corner? Well those mirror things are convex. The mirror ones that 'cave in' are concave. And they are different from a polygon because they really don't have sides like squares or rectangles:) Hope this helped.
What else can I help you with?
A pool is in the shape of a polygon. The segments and vertices of the polygon are shown. Is this polygon convex or concave?
concave
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.
Can a regular polygon be concave or convex?
no it cannot , because a regular polygon is a shape with equal sides, and for it to be concave or convex some sides have to jut out or in See related link below for more information

I think it is niether * * * * * A heptagon is simply a plane shape bounded by seven straight sides. Any polygon with three of more sides can be concave or convex.

Is a magnifying lens concave or convex in shape?

Having concave and convex edges terminating in points?
The described shape is a polygon with alternating concave and convex edges that meet at points. Some examples of polygons that match this description include stars, arrowheads, or certain irregular quadrilaterals.
What is the difference between concave and convex shapes and how can they be distinguished from each other?
Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
Is a star concave?
A geometric star shape is concave. A star that is in the sky is convex.
Is a concave shape a regular polygon?
no
What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
