Worksheet For ICSE Class 6 Maths Chapter 4 Geometry

Chapter : 4 Geometry

  Basic geometrical ideas (2 -D)

  • Basic geometrical ideas (2 -D)
  •   Introduction to geometry. Its linkage with and reflection in everyday experiences.

  • Line, line segment, ray
  • Open and closed figures
  • Interior and exterior of closed figures
  • Curvilinear and linear boundaries
  • Angle — Vertex, arm, interior and exterior
  • Triangle — vertices, sides, angles, interior and exterior, altitude and median
  • Quadrilateral — Sides, vertices, angles, diagonals, adjacent sides and opposite sides (only convex quadrilateral are to be discussed), interior and exterior of a quadrilateral
  • Circle — Centre, radius, diameter, arc, sector, chord, segment, semicircle, circumference, interior and exterior
  •   Understanding Elementary Shapes (2-D and 3-D):

  • Measure of Line segment
  • Measure of angles
  • Pair of lines – Intersecting and perpendicular lines, Parallel lines
  • Types of angles- acute, obtuse, right, straight, reflex, complete and zero angle
  • Classification of triangles (on the basis of sides, and of angles)
  • Types of quadrilaterals – Trapezium, parallelogram, rectangle, square, rhombus.
  • Simple polygons (introduction) (Upto octagons regulars as well as non-regular).
  • Identification of 3-D shapes: Cubes, Cuboids, cylinder, sphere, cone, prism (triangular and square), pyramid (triangular and square), Identification and locating in the surroundings.
  • Elements of 3-D figures. (Faces, Edges and vertices)
  • Nets for cube, cuboids, cylinders, cones and tetrahedrons
  •   Symmetry: (reflection)

  • Observation and identification of 2-D symmetrical objects for reflection symmetry.
  • Operation of reflection (taking mirror images) of simple 2-D objects
  • Recognising reflection symmetry (identifying axes).
  •   Constructions (using Straight edge Scale, protractor, compasses)

  • Drawing of a line segment
  • Perpendicular bisector
  • Construction of angles (using protractor).
  • Angle 60°, 120° (Using Compasses)
  • Angle bisector- making angles of 30°, 45°, 90° etc. (using compasses)
  • Angle equal to a given angle (using compass.)
  • Drawing a line perpendicular to a given line from a point a) on the line b) outside the line
  • Construction of circle.
