PPT-Polygons & Parallelograms

Properties amp Attributes A few polygons Triangle Quadrilateral much more on these later Pentagon Hexagon Heptagon Octagon Regular polygons are both equilateral and equiangular. 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 Section 8.5. Goal. Find the area of parallelograms.. Key Vocabulary. Base of a parallelogram. Height of a parallelogram. Parallelogram. Rhombus . Parallelogram. A parallelogram is a quadrilateral where the opposite sides are congruent and parallel.. 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. . “…geometric shapes are the alphabet in which the book of nature is written." -Galileo.
