Three vertices polygons (aka triangle) can not be concave or convex because it doesn't have enough verticies to susustain an internal angle is less than or equal to 180 degrees.

Actually, a triangle IS a convex polygon. Convexity requires angle to be less than 180 degrees and since the three angles of a triangle sum to 180 degrees, each one of them MUST be less than 180 degrees!
An equilateral triangle is NOT concave. The sides only push out, and they never cave in. An equilateral triangle is convex. I hope that helped all who needed.

A trapezoid is convex.
A non convex is a concave and a convex is differently shaped
Yes, a triangle is always concave. * * * * * How wrong can you get! A triangle is always convex and NEVER concave.

Well, isn't that a happy little question! A jeweller's mirror is usually concave, which means it curves inward like a bowl. This helps magnify the reflection and make it easier to see small details while creating beautiful pieces of art. Just remember, whether concave or convex, mirrors always reflect the beauty that's within you.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
It can be convex or concave.
convex and concave
Lenses: converging (convex) and diverging (concave) Mirrors: concave and convex
concave=in convex=out

A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
The Rear view mirrors are convex The Headlights are concave
The opposite of concave is convex. A concave surface curves inward, while a convex surface curves outward.
