102Re-entrant polygon — A re entrant, or concave polygon is one in which at least one interior angle is more than 180 degrees (i.e. a reflex angle). A polygon is re entrant or concave if there exist two points within the polygon which cannot be connected by a straight… …

106Constructible polygon — Construction of a regular pentagon In mathematics, a constructible polygon is a regular polygon that can be constructed with compass and straightedge. For example, a regular pentagon is constructible with compass and straightedge while a regular… …
107Isothetic polygon — An isothetic polygon is a polygon whose alternate sides belong to two parametric families of straight lines which are pencils of lines with centers at two points (possibly in the infinity). The most well known example of isothetic polygons are… …
108Bicentric polygon — In geometry, bicentric polygon is a circumscribed polygon which also has an inscribed circle (a circle that is tangent to each side of the polygon). All triangles and all regular polygons are bicentric. On the other hand, a rectangle with unequal …
109Midpoint-stretching polygon — In geometry, the midpoint stretching polygon of a cyclic polygon P is the polygon whose vertices are the midpoints of the circular arcs between the vertices of P.[1] It is also called the shadow of P. See also Maximal evenness Midpoint polygon… …
110convex polygon — noun 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 • Ant: ↑concave polygon • Hypernyms: ↑polygon, ↑polygonal shape * * * noun : a polygon each of whose angles is less… …
