2. VISUALISING SOLID SHAPES

3. WHAT ARE SHAPES? A shape is the form of an object or its external boundary , outline , or external surface , as opposed to other properties such as color , texture , or material composition. Psychologists have theorized that humans mentally break down images into simple geometric shapes called geons . Examples of geons include cones and spheres.

5. 2D shapes 2D shapes can be summarized by calling them flat shapes Any shape that can be laid flat on a piece of paper or any mathematical plane is a 2D shape. As a student , your fist drawings probably used basic shapes , such as squares , triangles , and circles

6. Examples of 2D shapes POLYGONS QUADRILATERALS CIRCLE TRIANGLE SQUARE RECTANGLE PENTAGON HEXAGON OCTAGON

7. 3D shapes These shapes are solid or hollow They have three dimensions Length Width Height

8. EXAMPLES OF 3D SHAPES CUBE CUBOID SPHERE CONE CYLINDER SQUARE BASE PYRAMID

9. IRREGULAR SHAPES Irregular shapes are two dimension structure which lies in a plane. These shapes will not have all slides equal and all angles equal. Irregular shape is denoted as when all the sides of the shapes having different length and the value of angles should not be same for all the angles. For better understanding we should know the difference between regular and irregular shapes. Regular shapes have equal angles and equal sides for example regular hexagonal , regular pentagon etc.

10. REGULAR SHAPES Regular shapes have equal angles and equal sides. For example: regular hexagonal , regular pentagon etc. Below are some examples of regular shapes and irregular shapes: Regular shapes: Above shapes , triangle , square , pentagon and hexagon , having some sides and same angles

12. MAP A map is a visual reprensentation of an entire area or a part of a area , typically represented on a flat surface. The work of map is to illustrate specific and detailed features of a particular area , most frequently used to illustrate specific and detailed features of particular area , most frequently used to illustrate geography. There are many kinds of maps; static , Two-Dimensional , Three Dimensional , dynamic and even interactive. Maps attempt to represent various things , like political boundaries , physical features , roads , topography , population , climates , natural resources and economic activities
