Pentagons (including convex pentagons) have five sides. (The prefix penta- is greek for 5)
the union of two convex sets need not be a convex set.
Magnifying mirrors, side mirrors on cars and trucks, certain securuty mirrors.
A convex polygon.I suspect that what you mean is a convex polygon.
convex
Convex mirrors are often used for side mirrors (if the mirror has a note saying "objects in mirror are closer than they appear," it's convex; it may be convex even without such a note).
The passenger's side mirror of a car is usually convex. This helps to provide a wider field of view and reduce blind spots.

Convex Mirror
No, that is not allowed in the US
You cannot solve a convex polygon! You can solve some questions regarding its angles, or side lengths or area or perimeter. But a convex polygon, in itself, is not something that can be solved!
Passenger-side auto mirrors are convex to provide a wider field of view, reducing blind spots and improving visibility of surrounding traffic. The convex shape helps to increase the viewing angle, making it easier to see objects that are located to the side and rear of the vehicle.
Concave mirrors are used in telescopes. Convex mirrors are used as side-view mirrors in cars.
because one side is concave and the other is convex
Its called a Convex Mirror
This gives the driver a wider field of vision. Usually only the passenger side mirror is convex. The reflective surface of a convex mirror curves outward like the outer surface of a ball or globe. An object observed by looking at its reflection in a convex mirror appears to be smaller than actual size.
A convex lens can converge a beam of parallel rays to a point on the other side of the lens. It is useful for reflecting and transmitting light.
