In this chapter, students will learn geometrical constructions using ruler and compass, focusing on accuracy and logical steps. They will learn how to divide a line segment in a given ratio and understand the importance of proportionality in constructions. The chapter also covers the construction of a triangle similar to a given triangle using a specified scale factor, which may be greater than 1 or less than 1.

Students will further learn how to construct a pair of tangents from an external point to a circle, applying properties of tangents studied earlier. This chapter strengthens practical geometry skills, enhances precision, and is highly important for CBSE Board practical understanding and diagram-based questions.
