a vertex
Any two adjacent sides on a polygon will form an included angle.
Any polygon with 5 or more sides can have that. Also, a square, rhombus, kite or arrowhead.
It is impossible to have a two-sided regular polygon with equal length sides. The two sides would merely form an open angle, with no closed third side.
Every polygon has two of its sides intersect.
They form a vertex of the polygon.
Any polygon can have, and every regular polygon has.

A regular polygon requires all sides to be the same length; in a rectangle not all four sides are the same length (they form two pairs of sides of equal length) and so it is not a regular polygon.
A polygon is a closed plane (flat) shape where an area is enclosed by a number of straight lines that meet, two at a time. These straight lines form the boundary of the polygon and are called its sides.
Yes, all trapezoids have 4 sides anyhow. The two right angles would have to be consecutive and the only right angles in the polygon to maintain a trapezoidal shape.
