A square is not a pentagon. Pentagons have 5 sides, squares have 4.
Yes it is. It is surely a polygon and convex means all interior angles are less than a straight angle ( i.e.180 degrees).
a polygon is convex
A non convex is a concave and a convex is differently shaped
A convex polygon is a polygon such that no side extended cuts any other side or vertex; it can be cut by a straight line in at most two points Example: A square is a convex polygon, as is an eqilateral triangle. A star shaped polygon is NOT convex. More generally, In Euclidean space, objects are convex if for every pair of points within the object, every point on the straight line segment that joins them is also within the object.
A parallelogram need not be a square, it need not be a rhombus but it is a convex shape.
A square is not a pentagon. Pentagons have 5 sides, squares have 4.
A polygon is convex if it has no two points that can be used to define a line segment that falls outside of that polygon. Another way to put it is: a convex polygon has all vertices pointing 'out'. Consider the following 6-sided polygon: _ ' | |_ |__| Well you get the idea. The 'notch' cut out of the square turns the square into a six sided figure now, with the 'corner' in the upper right pointing 'in' so the polygon is not convex.
Yes it is. It is surely a polygon and convex means all interior angles are less than a straight angle ( i.e.180 degrees).
Yes, if a quadrilateral has 4 congruent sides and 4 congruent angles, it is a square. Since it is a square, all angles are 90o. Since there are no angles above 180o, it is convex.
a polygon is convex
A convex polygon with congruent sides and congruent angles is a regular polygon.Some regular pilgrims have specific names: Equilateral triangle and square

No. There can be no regular concave polygon.

A square pyramid.If you would like to be abstruse you could call it the first Johnson solid (a non-uniform convex polyhedron).
