Quick Answer
Class 8 Mathematics Chapter 10 Practical Geometry covers compass and straightedge constructions of triangles, quadrilaterals, parallelograms, rhombuses, and regular polygons, along with angle bisectors, incircles, and circumcircles. On this page, Federal Board Grade 8 students can access complete solved textbook exercises, conceptual MCQs, short questions, and step-by-step construction instructions aligned with the 2026-2027 NBF curriculum.
Chapter Overview
Chapter 10 develops students' precision in ruler-and-compass geometric constructions, emphasizing mathematical accuracy and systematic draughtsmanship. Students learn standard protocols for constructing various triangles given different data conditions: three sides (SSS), two sides and the included angle (SAS), two angles and the included side (ASA), and right-angled hypotenuse-side (RHS).
The chapter extends to constructing specialized line segments and circles associated with triangles, including angle bisectors, medians, perpendicular bisectors, the circumscribed circle (circumcircle), and the inscribed circle (incircle). Students master identifying the point of concurrency (circumcenter and incenter) through precise arc intersections and radius determinations.
Additionally, the unit covers constructing special quadrilaterals-such as parallelograms, rhombuses, rectangles, and kites-from given dimensions of sides, diagonals, and included angles. It concludes with methods for inscribing and circumscribing regular polygons (squares, regular hexagons, and octagons) within circles. All textbook review exercises and construction steps are provided with clear procedural instructions aligned with FBISE SLO criteria.
