Introduction to Constructions in CBSE Class 10 Maths

The chapter Constructions is a key part of CBSE Class 10 Geometry. It focuses on drawing geometric figures accurately using a compass, ruler, and protractor based on given conditions. Mastery of constructions is essential as it combines theoretical knowledge with practical geometry skills, which are frequently tested in board exams.

Importance of the Constructions Chapter

Constructions are scoring and carry high weightage in board exams. Questions in this chapter test a student’s understanding of geometrical principles, accuracy, and step-by-step construction skills. Students learn to construct:

• Triangles using sides and angles

• Tangents to circles

• Perpendicular bisectors and angle bisectors

• Quadrilaterals based on given conditions

Practicing constructions enhances precision, problem-solving skills, and visualization ability.

Key Concepts Covered in Constructions

The chapter emphasizes several important concepts:

1. Constructing Triangles:

   • Using SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), and RHS (Right angle-Hypotenuse-Side) criteria

2. Bisectors:

   • Constructing perpendicular bisectors of a line segment

   • Constructing angle bisectors of a given angle

3. Tangents to Circles:

   • Drawing tangents from an external point

   • Drawing tangents using radius and perpendicular line at the point of contact

4. Constructions Related to Quadrilaterals:

   • Constructing a quadrilateral given sides and diagonals or angles

5. Division of a Line Segment:

   • Dividing a line segment in a given ratio

Each of these topics is exam-oriented, requiring both precision and proper methodology.

Types of Questions in Constructions Chapter

From previous year papers, common question types include:

• Constructing a triangle using given sides and angles

• Drawing perpendicular bisectors and angle bisectors

• Constructing tangents from an external point to a circle

• Constructing quadrilaterals based on given dimensions and diagonals

• Dividing a line segment in a given ratio

Students must follow step-by-step procedures to ensure accuracy and earn full marks.
