A convex shape.
Most all corrective lenses are convex. Anything round, or even just "roundish" has a convex shape. From bowling balls to chickens' eggs, they are all convex, or "rounded outward" in shape.
it is a shape with 180degrees or less
Take any two points on or inside a body. If every point on the straight line joining the two points lies within the shape, then it is convex. If not, it is non-convex.
I believe the fewest number of sides in a planar, non-convex polygon is four.
A convex shape is a shape that is pushing out like a house -> /\ <- |_|

A parallelogram need not be a square, it need not be a rhombus but it is a convex shape.
No. Convex simply means that if you have a straight line segment joining any two points in (or on) a convex shape, then every point on that line segment in inside or on the shape. A convex shape can have 2 or more dimensions, it can by a polygon or have curved sides.

A parallelogram cannot be generalised to a convex shape with an odd number of sides.

Convex. The hearts inward point makes this so.
Convex is usually bigger than concave. In a convex shape, an imaginary line connecting any two points lies completely within the shape, making it appear more expansive. In contrast, a concave shape curves inward, often providing less surface area than a convex shape of similar dimensions.
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
