THREE DIMENSIONAL POLYGONS
 THREE DIMENSIONAL POLYGONS Notes Code: MT160601ES AN OVERVIEW OF 3 DIMENSIONAL FIGURES   What is a three dimensional figure? In short 3D figure Any polygon which can be measured in three directions is called a 3D figure; they are also known as solid shapes. The below diagrams show different 3D shapes In our everyday day life, there are different things we use which are in form of 3D shapes these things are such as: Ball (sphere), Rubik’s Cube (Cube), Box (Cuboid/Cube), a mug (Cylinder), a birthday cap (cone) etc. The picture below shows some of real objects we use in everyday life which are in form of 3D shapes: CHARACTERISTICS OF 3D SHAPES Unlike 2D shapes, the 3D shapes have the following characteristics: Three-dimensional shapes have faces, edges and vertices. The flat surfaces of the 3D shapes are called the faces. The line segment where two faces meet is called an edge. A vertex (Plural Vertices) is a point where 3 edges meet. A common vertex where all edges of a pyramid meet is called an Apex. See the picture below: The below table shows every 3D shape with its attributes: Thanks for learning, See you next part SURFACE AREAS OF 3D SHAPES. ************** END ****************** In case of any question or comment be free to write down: A lot of Thanks Mr. Yahya M (Badshah)   ****** MT160601ES ******* .u-star-rating-16 { list-style:none;margin:0px;padding:0px;width:80px;height:16px;position:relative;background: url('/.s/t/1706/rating.png') top left repeat-x } .u-star-rating-16 li{ padding:0px;margin:0px;float:left } .u-star-rating-16 li a { display:block;width:16px;height: 16px;line-height:16px;text-decoration:none;text-indent:-9000px;z-index:20;position:absolute;padding: 0px;overflow:hidden } .u-star-rating-16 li a:hover { background: url('/.s/t/1706/rating.png') left center;z-index:2;left:0px;border:none } .u-star-rating-16 a.u-one-star { left:0px } .u-star-rating-16 a.u-one-star:hover { width:16px } .u-star-rating-16 a.u-two-stars { left:16px } .u-star-rating-16 a.u-two-stars:hover { width:32px } .u-star-rating-16 a.u-three-stars { left:32px } .u-star-rating-16 a.u-three-stars:hover { width:48px } .u-star-rating-16 a.u-four-stars { left:48px } .u-star-rating-16 a.u-four-stars:hover { width:64px } .u-star-rating-16 a.u-five-stars { left:64px } .u-star-rating-16 a.u-five-stars:hover { width:80px } .u-star-rating-16 li.u-current-rating { top:0 !important; left:0 !important;margin:0 !important;padding:0 !important;outline:none;background: url('/.s/t/1706/rating.png') left bottom;position: absolute;height:16px !important;line-height:16px !important;display:block;text-indent:-9000px;z-index:1 } Category: Upper Primary | Added by: Admin (26/Jun/2017) | Author: Yahya Mohamed E W Views: 238 | | Rating: 0.0/0
