Geometrical Construction is the process of drawing geometrical figures using only two objects – a ruler and a compass. This chapter is practical-oriented. Here, students will learn how to draw two lines at different angles using tools.

Moving forward, you will also draw triangles on the given base length, side length, and base angles. In the end, you will be able to draw the perpendicular bisector of a given line segment, construct an angle of 60°, construct a triangle given its base, a base angle and the sum of the other two sides, and construct a triangle given its base, a base angle and the difference of the other two sides, construct a triangle given its perimeter and its two base angles.

This chapter requires a lot of practice. If students practice more, it will be easy for them to attempt all the questions from this chapter with complete accuracy. Students can also check the table below to find out the important topics covered in NCERT Class 9 Maths Chapter 11:
