Polygons can be classified in a number of ways.
A convex polygon is one in which a straight line joining any two points inside the polygon lies wholly inside the polygon. One consequence is that all its interior angles are less than 180 degrees. A concave polygon is one in which at least one angle is a reflex angle (> 180 deg). Generally, a polygon may be assumed to be convex unless otherwise specified.
A regular polygon is one in which all the sides are of equal length AND all the angles are of equal measure. An irregular polygon is one in which at least one side is of a different length from the others OR at least one angle is of a different measure from the others.
Polygons can have three or more sides. There is no limit to the number of sides that a polygon may have.
The interior angle of a polygon is pre-determined only if it is regular. In a regular polygon with n sides, each interior angle has a measure of
180*(n-2)/n degrees.
A regular triangle [equilateral] is acute angled; a regular quadrilateral [square] is right angled and all other regular polygons are obtuse angled.
You cannot "solve the kinds of polygons". There are essentially three types of polygons: Regular polygons in which each angle is the same and each side is the same. Irregular convex polygons in which at least one angle or one side are different but there are no reflex angles. Concave polygons in which there is at least one reflex angle. Convex and concave are usually defined in terms of whether or not the enclosed space is closed, but the above definitions may be simpler to grasp.
There are several types of polygons, including regular polygons, which have equal sides and angles, such as a square or equilateral triangle. There are also irregular polygons, which have different side lengths and angles, such as a rectangle or pentagon. Finally, there are convex polygons, where all interior angles are less than 180 degrees, and concave polygons, where at least one interior angle is greater than 180 degrees.
If you meant "What kinds of polygons are there?", all I can say is that the number of sides ranges from 3 to infinity. And then, the angle can vary. So there are many different types of polygon, but to the end, there is one thing common to all is that the exterior angle for all polygons is always 360 degrees.
all regular polygons
A polygon is a shape that is a closed figure and has straight lines. example. A square
Right angle (900) Acute angle (less than 900) Obtuse angle (greater than 900)
There are many different kinds of kites, so likely there is a kite with an acute angle.
