Topic 1: Points<\/h3>\n\n\n\n
    \n
  • Point:<\/strong> A point determines a location. If you mark three points on a paper, you will be required to distinguish them. For this, they are denoted by a single capital letter like A, B, and C.<\/li>\n<\/ul>\n\n\n\n

    Topic 2: Line Segment<\/h3>\n\n\n\n
      \n
    • Line Segment:<\/strong> A line with a definite length, i.e. it has two endpoints on either end is called a line segment. The two endpoints, say A and B (including A and B) denote the line segment by AB or BA with a (–) on top.<\/li>\n<\/ul>\n\n\n\n

      Topic 3: Line<\/h3>\n\n\n\n
        \n
      • Line: <\/strong>A line has no endpoints and has an infinite number of points. A line through points A and B can be represented as AB with a (\u2194) on top.<\/li>\n<\/ul>\n\n\n\n

        Topic 4: Intersecting Lines<\/h3>\n\n\n\n
          \n
        • Intersecting Lines:<\/strong> Two lines having a common point are called intersecting lines. <\/li>\n<\/ul>\n\n\n\n

          For eg, let us consider two lines l1 <\/sub>and l2<\/sub> intersecting at a point P will be represented as:<\/p>\n\n\n\n

          Topic 5: Parallel Lines<\/h3>\n\n\n\n
            \n
          • Parallel Lines:<\/strong> Lines that do not have a common point or the lines that do not meet are called parallel lines. <\/li>\n<\/ul>\n\n\n\n

            For eg, the lines A, B and C given below are parallel lines. <\/p>\n\n\n\n

            Topic 6: Ray<\/h3>\n\n\n\n
              \n
            • Ray: <\/strong>A ray is a portion of a line, it starts at one point (called a starting point) and goes endlessly in a direction.<\/li>\n<\/ul>\n\n\n\n

              Topic 7: Curves<\/h3>\n\n\n\n
                \n
              • Curves:<\/strong> Curve\u2019 in everyday usage means \u201cnot straight\u201d. If a curve does not cross itself, then it is called a simple curve.<\/li>\n\n\n\n
              • Open Curve:<\/strong> When a curve does not make a closed shape.<\/li>\n<\/ul>\n\n\n\n
                \"\"<\/figure>\n\n\n\n
                  \n
                • Closed Curve:<\/strong> When a curve makes a closed shape\/figure. <\/li>\n<\/ul>\n\n\n\n
                  \"\"<\/figure>\n\n\n\n

                  Topic 8: Polygons<\/h3>\n\n\n\n
                    \n
                  • Polygons: <\/strong>Any closed shape formed solely by line segments is called Polygons.<\/li>\n<\/ul>\n\n\n\n

                    For eg, <\/p>\n\n\n\n

                    \"\"<\/figure>\n\n\n\n
                      \n
                    • Sides: <\/strong>The line segments forming a polygon are called its sides.<\/li>\n\n\n\n
                    • Vertices: <\/strong>The meeting point of a pair of sides is called its vertex. <\/li>\n\n\n\n
                    • Diagonal: <\/strong>Consider the pairs of vertices which are not adjacent. The joins of these vertices are called the diagonals of the polygon.<\/li>\n<\/ul>\n\n\n\n

                      Topic 9: Angles <\/h3>\n\n\n\n
                        \n
                      • Angles: <\/strong>Angles are made when corners are formed. Note that in specifying the angle, the vertex is always written as the middle letter.<\/li>\n<\/ul>\n\n\n\n

                        For eg, the angle formed by rays OP and OQ is \u2220POQ. <\/p>\n\n\n\n

                        Topic 10: Triangles<\/h3>\n\n\n\n
                          \n
                        • Triangles: <\/strong> A triangle is a three-sided polygon.<\/li>\n<\/ul>\n\n\n\n
