We can study the three dimensional shapes and their properties with the help of three dimensional coordinate system.It is used for geometric representation of three dimensional shapes like cube, sphere, cylinder, cone etc.Two dimensional Coordinate system (Cartesian coordinate system) Three dimensional coordinate system: The x and y coordinates are the intercepts made by the object on that axis respectively.įig.The two dimensional geometric figure like circle, ellipse, hyperbola, curves, straight lines, quadratic equations, different types of charts are explained with the help of XY-coordinate system.In this way, we can represent any two dimensional object in XY-plane.The following figure shows the two dimensional coordinate system in which a line is located with the points on it.And in fourth quadrant, X is positive and y is negative.In third quadrant, x and y both are negative.In second quadrant x is negative and y is positive.In first quadrant, x and y both are positive.In two dimensional coordinate system, we can locate two dimensional shapes withe each point on them in two coordinate form.Three dimensional objects have faces, edges and vertices also.Two dimensional objects are located in two dimensional coordinate system.Solid geometry involves all the three dimensional shapes and their properties also.Two locate three dimensional shapes in geometry we use three dimensional coordinate system i.e.with their properties such as surface area, volume etc. Solid geometry involves all the three dimensional shapes like cube, sphere, cylinder, cone, prism etc.Two dimensional object does not possess faces and edges, they have only sides and vertices.Polygon and their types also involves in plane geometry.The shapes in two dimensions has only sides, perimeter and area.Plane geometry involves types of lines, types of angles, types of triangles and their properties.We can define or locate all two dimensional shapes in XY-plane.We can locate the two dimensional shapes in two dimensional coordinate system in XY-plane.Also, it includes perimeter, area of these shapes also.The two dimensional shapes are square, rectangle, triangle, circle etc.Plane geometry involves the shapes or objects which are two dimensional.While solid can be represented in three dimensional coordinate system only. We can represents point, line and plane in two dimensional coordinate system. Now we see in detailed about plane geometry and solid geometry. Finally, solid means a three dimensional shapes which is having 3 coordinates.Plane is the two dimensional shape having two coordinates.Line is the one dimensional shape which is locus of points along straight path.A point is having no dimension and it has only its position.Point, line, plane and solid are the basics shapes of geometry.The mainly geometry can be studied in two parts, plane geometry and solid geometry.īefore going to learn about plane and solid geometry we see some basic shapes of geometry. It involves all shapes, their properties, solids, perimeter, area, volume, surface area of solid surfaces and shapes, coordinate system and all theorems based on it.
We are not only learning the geometry but also playing with geometry from our childhood.
