International Math Olympiad is a competitive examination for students who excel in the subject. Students competing in Math Olympiads can assess their knowledge of the subject and determine where they stand in comparison to their peers at the national and international levels. Furthermore, the exam assists students in gaining a competitive advantage.

Olympiad tests are subject-centered cutthroat competitions held on a larger normal stage across the world. Understudies from various nations and schools compete at a higher level of learning and becoming together to help them get where they remain among friends of a similar instructional level. 

There are Olympiads for various subjects like:

 International Science Olympiad (ISO)

International Math Olympiad (IMO)

International English Olympiad (IEO)

International General Knowledge Olympiad (IGKO)

Understudies can choose to participate in one or more of these Olympiads based on their availability. These tests are designed to elicit genuine ability from students, assist them in building certainty, and prepare them for comparative cutthroat tests.

IMO Class 4 Chapter 6: Geometrical Concepts Detailed Notes

Fundamental Geometrical Ideas

  • 2D Shapes
  • 3D Shapes

Geometry (Point, Line, Ray, Line Segment)

Making Shapes with a Net

A net is a flat, two-dimensional pattern that can be folded into a three-dimensional shape; when the three-dimensional shape is undone, the net is revealed. There could be several nets in a solid.

Point to keep in mind:

  • The same number of faces exists in both the solid and its net.
  • Consider how the net might be folded to take on the specified shape.


A point is a very tiny dot that can be made with a pencil. They are neither large nor small. To name a point, use a capital letter.

See the illustration below. Point O is this.

Line Segment

A line segment is a straight path that connects two points.

A line segment is demonstrated in the image below. Line segment AB refers to this section of the line.

A line is a segment of a line that never ends on either side. It doesn’t have a start or finish.


A ray is a segment of a line that never ends and travels exclusively in one direction.


A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be extended indefinitely in opposing directions. Two points in a two-dimensional plane determine it. Collinear points are two points that are located on the same line.

How to Prepare for a Math Olympiad

When a student is taking a competitive exam, such as the International Math Olympiad, preparation is especially important. School Connects Online introduced Math Olympiad Workbooks and Previous Year Question Papers for students in grades 1 through 10. The study materials are created by subject matter experts.
