PPT-6.1 properties and attributes of Polygons

Characteristics of a Polygon Decide if each shape is a polygon or not Polygon Not a Polygon Convex Polygons Line segments do not extend into itself Concave Polygons Line segments DO extend into itself. In rendering complex 3D images it has to be done several thousand times Ef64257cient algorithms are therefore very important We present such an ef64257cient algorithm for clipping arbitrary 2D polygons The algorithm can handle arbitrary closed polyg What are similar polygons?. Two polygons are similar if corresponding (matching) angles are congruent and the lengths of corresponding sides are proportional.. Congruent Figures. In order to be congruent, two figures must be the same size and same shape.. Lasse Deleuran. PhD student. Content. Motivation. Our . Results. Restricted simplification. Unrestricted simplification.

NOT A POLYGON. POLYGONS. POLYGONS. Polygons may also be called 2D shapes or PLANE FIGURES. . Polygons. Unit of Study . 10. : Plane Shapes. Global Concept Guide: 2 of 4. Content Development. Students need opportunities to define shapes based on attributes. Example: a triangle is any closed figure made up of three line segments that connect only at vertices.. I can identify different types of polygons.. I can tell the properties of each type of polygon.. I can categorize quadrilaterals based on their properties.. Polygon Review. SRB 142.
