Class 6 Maths - PUNJAB
Playing with Constructions
The chapter Playing with Constructions in Class 6 Mathematics under the Punjab School Education Board (PSEB) introduces students to the exciting world of geometric drawing using basic tools like a ruler, compass, divider, set-squares, and protractor. Students learn the step-by-step methods to draw fundamental geometric shapes accurately. This includes constructing a line segment of a given length, copying a line segment, constructing perpendicular lines, perpendicular bisectors, and angles of various measurements like 60, 90, and 45 degrees using a compass and ruler. Mastering these foundational techniques is crucial for higher-level geometry and scores high in board exams.

Line Segment Construction
Drawing a straight path between two fixed endpoints of an exact given length using a ruler and compass.
Perpendicular Bisector
A line that divides a given line segment into two equal halves at exactly a 90-degree right angle, constructed using a compass.
Constructing Angles with Compass
Drawing standard angles such as 60 degrees, 120 degrees, and their angle bisectors like 30 and 45 degrees without using a protractor.
Angle Bisector
A ray that divides a given angle into two completely equal smaller angles using compass arcs.
Perpendicular to a Line
Drawing a line at a 90-degree angle to another line, either passing through a given point on it or a point outside it.

Board Exam Info
In the Punjab (PSEB) Class 6 Mathematics examination, this chapter typically carries around 6 to 8 marks. Common question types include step-by-step construction of specific angle measurements using a compass, drawing perpendicular bisectors of line segments, and writing the procedural steps of construction.
Frequently Asked Questions
Can I use a freehand drawing for geometric constructions in PSEB exams?
No, all geometric constructions must be drawn strictly using proper mathematical instruments like a sharp pencil, ruler, and compass. Neatness and visible construction arcs are essential for full marks.
Is it mandatory to write the steps of construction?
Yes, whenever a question asks to construct a shape or angle, writing brief, numbered steps of construction alongside the diagram is usually required to secure full marks.
Why should we use a compass for angles instead of a protractor?
Compass constructions are geometric methods that provide exact precision and help develop spatial reasoning, which is tested in standard construction problems.
