I assume you mean "angles". As many as you want (at least 3).

polygon
Any polygon has the same number of angles as its sides.
That is called a regular polygon.
Isogon
Yes if it is a 5 sided pentagon polygon
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
Providing that it's a regular polygon it will have 36 sides because 360/10 = 36
The number of angles on a polygon is the same number of sides the shape has.
A trapezoid.
a quadrilateral
square :)
