(i) Basic geometrical ideas (2 -D)- Basic geometrical ideas in two dimensions (2D) include points, lines, line segments, rays, angles, triangles, quadrilaterals, circles, and polygons. Here is a brief explanation of each concept:
- Points: A point is a location in space and has no size or dimensions. It is typically represented by a dot.
- Lines: A line is a straight path that extends infinitely in both directions. It is defined by at least two points. It has no thickness.
- Line segments: A line segment is a part of a line that consists of two endpoints and all the points in between them.
- Rays: A ray is a part of a line that starts from a single point (the endpoint) and extends infinitely in one direction.
- Angles: An angle is formed when two rays share a common endpoint called the vertex. It is typically measured in degrees and denoted by the symbol “°.”
- Triangles: A triangle is a polygon with three sides. It is formed by connecting three non-collinear points.
- Quadrilaterals: A quadrilateral is a polygon with four sides. Examples include squares, rectangles, parallelograms, trapezoids, and rhombuses.
- Circles: A circle is a set of points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius.
- Polygons: A polygon is a closed figure with three or more sides. The sides are line segments, and the vertices are points where the sides intersect.
These basic geometrical ideas form the foundation of two-dimensional geometry and are essential for understanding more complex geometric concepts and theorems.

Case Study on Class 6 Maths (i) Basic geometrical ideas (2 -D)
Title: Designing a School Garden
Introduction: In this case study, we will explore how the basic geometrical ideas (2-D) taught in Class 6 Mathematics can be applied to design a school garden. The purpose is to demonstrate the practical application of geometric concepts in a real-life scenario.
Scenario: ABC School wants to create a beautiful and functional garden on its premises. The school administration wants the garden to have different sections, each with specific features such as flower beds, pathways, and a seating area. The Class 6 students, along with their mathematics teacher, are given the task of designing the school garden using their knowledge of basic geometrical ideas.
Application of Basic Geometrical Ideas:
- Identifying and Representing Shapes: The students start by identifying the available space for the garden and representing it on graph paper. They use their understanding of lines, line segments, and angles to accurately draw the boundaries of the garden.
- Planning Pathways: The students decide to incorporate curved pathways that connect different sections of the garden. They utilize their knowledge of circles, radii, and arcs to plan and draw the pathways with appropriate dimensions and curvatures.
- Creating Flower Beds: The students determine the locations for flower beds within the garden. They apply their understanding of shapes, such as rectangles and circles, to design the flower beds and ensure they are symmetrically placed. They calculate the area of each flower bed using the formulae they have learned.
- Designing Seating Area: The students allocate an area for a seating area in the garden. They use their knowledge of shapes, such as squares and rectangles, to design benches and tables for the seating area. They also consider the placement of the seating area to ensure it is centrally located and easily accessible.
- Applying Symmetry: The students apply the concept of symmetry to create a visually appealing garden. They use the mirror image property of shapes to make sure the garden design is balanced and harmonious. For example, they ensure that flower beds on one side of the pathway are mirrored by corresponding flower beds on the other side.
- Estimating Dimensions: The students estimate the dimensions of different elements in the garden, such as the width of pathways, the size of flower beds, and the spacing between benches. They use their understanding of measurements, angles, and proportions to make accurate estimates that fit well within the available space.
Conclusion: By applying their knowledge of basic geometrical ideas (2-D), the Class 6 students successfully design a beautiful and functional school garden. They effectively utilize concepts such as shapes, symmetry, measurements, and proportions to plan and create different elements of the garden. This case study demonstrates the practical application of geometry in designing real-life spaces and highlights the importance of basic geometrical ideas in various design and planning scenarios.
