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 Remark: Discusses “basics concerning data sets (first half of Chapter 2) but does not discuss preprocessing. Preprocessing will be discussed in . late October. . What is Data?. Collection of data objects and their attributes. for Polygonal Meshes. Δ. Marc Alexa Max . Wardetzky. TU Berlin U . Göttingen. . Laplace Operators. Continuous. Symmetric, PSD, linearly precise, maximum principle. Discrete (weak form). BUILDING POLYGONS. We use line segments to build polygons. . A polygon is a closed shape with straight sides.. POLYGON. 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. Notes and Definitions. M.C. Escher. Similar Polygons.

Diagonal – connects two non consecutive vertices. Concave – at least one diagonal outside polygon, dented in. Polygon: A closed plane figure with 3 or more sides (line segments) that intersect only at the endpoints.. Vertex: Each endpoint of a side of a polygon.. Convex Polygon: A polygon such that . no line. Classifying Polygons. Students . will be able . to:. Identify the 2-dimensional shapes based on their properties.. Key Vocabulary. Polygons. Triangles.
