![]() ![]() A map is given showing some landmarks of a city. It reduces the real distances proportionately to distances on the paper.Įxample 1. Maps use a scale which is fixed for a particular map. For example, look at the following illustration.Ĥ. There is no reference or perspective in map, i.e., objects that are closer to the observer are shown to be of the same size as those that are farther away. Symbols are used to depict the different objects/places.ģ. A map depicts the location of a particular object/place in relation to other objects/places.Ģ. The larger the place and smaller the size of the map drawn, the greater is the distance represented by 1 cm.ġ. ![]() That is 1 cm of space in the map of Delhi will represent smaller distances as compared to the distances in the map of India. You will find that when the maps are drawn of same size, scales and the distances in the two maps will vary. This scale can vary from map to map but not within a map.įor instance, look at the map of India alongside the map of Delhi. This means, that if one draws a map, he/she has to decide that 1cm of space in that map shows a certain fixed distance of say 1 km or 10 km. While drawing (or reading) a map, one must know, to what scale it has to be drawn (or has been drawn), i.e., how much of actual distance is denoted by 1mm or 1cm in the map. This is done by considering a proper scale. Observe that the distances shown on the map are proportional to the actual distances on the ground. Thus we realise that, use of certain symbols and mentioning of distances has helped us read the map easily. Which are the important landmarks on the route ? Whose school is nearer to the house, Raghav’s or Meena’s ?ģ. How far is Raghav’s school from his residence ?aĢ. Now, you can answer the following questions :ġ. Secondly, longer line segments have been drawn for longer distances and shorter line segments have been drawn for shorter distances, i.e., she has drawn the map to a scale. Here, Meena has used different symbols for different landmarks. This map is different from the earlier maps. Now look at another map drawn by his sister, ten year old Meena, to show the route from her house to her school. The reason is that we do not know if the distances have been drawn properly or whether the circles drawn are roundabouts or represent something else. It is very difficult to answer the above questions on the basis of the given map. (iii) whose school is nearer to the house, Raghav’s or his sister’s ? (ii) would every circle in the map depict a round about ? (i) how far is Raghav’s school from his house ? Now, look at the adjacent map, which has been drawn by seven year old Raghav, as the route from his house to his school : In other words, perspective is very important for drawing a picture but it is not relevant for a map. The map of the house remains the same irrespective of the position of the observer. But, this is not true in the case of a map. Secondly, different persons can give descriptions of pictures completely different from one another, depending upon the position from which they are looking at the house. What can we conclude from the above illustration? When we draw a picture, we attempt to represent reality as it is seen with all its details, whereas, a map depicts only the location of an object, in relation to other objects. Look at the map of a house whose picture is given alongside. You have traced routes of rivers, roads, railway lines, traders and many others. In History, you might have been asked to locate a particular place where some event had occured long back. In Geography, you have been asked to locate a particular State, a particular river, a mountain etc., on a map. How do they look like ?įor each of the given solid shapes, the three views are given : ![]() Let us view a brick from front, side and top. Sol : After matching figures with their names are as the follow : (i) Match the 2 dimensional figures with the names Sol : After matching the shape with their names are as follow (i) In this chapter, we learn about various three-dimensional objects. That is, they all occupy space and have three dimensions. Three dimensional objects is that they all have some length, breadth and height or depth. Plane figures are of two dimensions (2–D) and the solid shapes are of three-dimensions (3–D). The circle, the square, the rectangle, the quadrilateral and the triangle are examples of plane figure the cube, the cuboid, the sphere, the cylinder, the cone and the pyramid are the examples of Solid Shapes. ![]()
