Information about visualising solid shapes

Answer 1

isualising solid shapes1. What Are Shapes? A shape is a geometrical figure that can be described with mathematics. One way to classify shapes is to describe a bigger shape that the shape fits inside of. For example, two-dimensional shapes like circles will fit inside of a flat plane. Three-dimensional objects like cubes will not fit inside of a plane, because they are not flat.2. 2-dimensional Shapes These are twodimensional shapes or flat plane geometry shapes. Their sides are made of straight or curved lines. They can have any number of sides. Plane figures made of lines are called polygons. Triangles and squares are examples of polygons3. Properties Of 2 Dimensional Shapes Two-dimensional shapes are planar. Graphically speaking, they depend on only two coordinates--x and y, for instance-consisting of x units and y units, respectively. In the case of a coordinate system of more than two dimensions, then a 2-D shape would still depend on two coordinate directions. For example, in a spatial xyz coordinate system (which is threedimensional) a two-dimensional shape would be expressed with points such as (x,y,0), (x,0,z), or (0,y,z). Therefore, it would depend on either x and y, x and z, or y and z. 2-D shapes include the square, the triangle, the rhombus, etc. To understand it more easily, you can say that 2-D shapes do not have prominent or rugged parts. For example, speaking two-dimensionally you would have a square, whereas threedimensionally you would have a cube, which is like an extended or prominent square.4. 3-Dimensional Shapes A 3D shape is a solid which encloses a volume and has length, breadth and height5. Other 3D shapes6. Properties Of 3 Dimensional Shapes Three-dimensional shapes have four properties that set them apart from two-dimensional shapes: faces, vertices, edges and volume. These properties not only allow you to determine whether the shape is twoor three-dimensional, but also which three-dimensional shape it is.7. What is a Map? A map is a graphic representation of a portion of the earth's surface drawn to scale, as seen from above. It uses colors, symbols, scales and labels to represent features found on the ground.8. Colors used in Map a. Black. Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels. b. Red-Brown. The colors red and brown are combined to identify cultural features, all relief features, non-surveyed spot elevations, and elevation, such as contour lines on red-light readable maps. c. Blue. Identifies hydrography or water features such as lakes, swamps, rivers, and drainage. d. Green. Identifies vegetation with military significance, such as woods, orchards, and vineyards. e. Brown. Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps. f. Red. Classifies cultural features, such as populated areas, main roads, fire station,and boundaries, on older maps. g. Other. Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule.

Answer 2

Answer:-

Measurements like length and breadth are therefore there are called two dimensional shapes where is a solid object has three measurements like Length breadth height and depth hence they are called dimensional shapes ,also object solid occupation space to Diamond shapes and 3D shapes figures can also briefly named as 2D and 3D figures this together called as reading solid shapes
