May 7, 2024 · 2. Irregular Polygon. An irregular (or complex) polygon has at least one interior angle that does not match the rest. Line segments with different lengths cause this outlier point to stretch the shape, causing non-consecutive vertices where the diagonals meet. 3. Convex Polygon. All convex polygons fall into the regular polygon category.

Concave Polygons. Concave polygons are those polygons in which at least one interior angle is a reflex angle and it points inwards. They have a minimum of 4 sides and a few of the diagonals in a concave polygon may lie partly or fully outside it. All concave polygons are irregular because the interior angles are not equal.

It is the total space enclosed within the polygon. The formula is given below: Area (A) = ½|(x1y2 – x2y1)+(x2y3– x3y2)+……..+(xny1– x1yn)|, here (x1, y1), (x2, y2), (x3, y3),…….., (xn, yn) are the vertices of the polygon on the coordinate plane
The interior angles of a polygon are the angles found inside the polygon. A polygon has the same number of interior angles as the number of sides. Sum of the Interior Angles It is the total measure of all the interior angles combined in the polygon. The formula to determine the sum of all angles in any convex regular polygon is given below: Sum of ...
The exterior angle of a polygon is the angle formed by one side and the extension of the adjacent side. The exterior angle sum theorem states that the sum of the exterior angles of any convex polygon is 360°. For regular convex polygons having n sides, each exterior angle is determined using the following formula: Exterior angle of a Convex Regular...
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon (straight sides) Not a Polygon (has a curve) Not a Polygon (open, not closed) Polygon comes from Greek. Poly- means "many" and -gon means "angle".
A concave polygon is a polygon in which at least one interior angle is a reflex angle (angle greater than 180° but less than 360°). A concave polygon has at least 4 sides. It means that a triangle is always a convex polygon. The diagonals in a concave polygon may lie partly or fully outside the polygon.
Irregular polygons have a few properties of their own that distinguish the shape from the other polygons. The properties are: An irregular polygon does not have equal sides and angles. Irregular polygons can either be convex or concave in nature. Irregular polygons are shaped in a simple and complex way.

A Concave polygon is a polygon that has at least one interior angle greater than 180 degrees. It must have at least four sides. The shape of the concave polygon is usually irregular. A concave polygon is a polygon which is not convex. This polygon is just the opposite of a convex polygon. A simple polygon is considered as a concave polygon if ...
