Video description and outline Title: Selina Class 10 Maths \| Chapter 16 Loci (Locus & Construction) \| Solved Examples Description: This video provides a comprehensive guide to Selina's Class 10 Maths, Chapter 16: Loci (Locus and its Constructions). Learn to define and visualize loci, understand their geometric properties, and master the construction of various loci for moving points. We'll cover key concepts like: The fundamental definition of a locus as a path traced by a moving point satisfying certain conditions. Geometric examples of loci, such as circles, parallel lines, and the locus of the center of a wheel. Step-by-step instructions for constructing loci, including the perpendicular bisector and angle bisector, based on Selina's exercises. Solutions to practice problems to help you build your skills for the ICSE exams. Video content and structure Introduction Define "locus" as the set of points that satisfy a given condition. Introduce the basic idea of a moving point and the path it traces. Part 1: Locus - Definition and Examples Example 1: Locus of a point at a fixed distance from a fixed point is a circle. Show how to draw it. Example 2: Locus of a point at a fixed distance from a fixed line is a pair of parallel lines. Illustrate the construction. Example 3: Locus of the center of a wheel of a bicycle going straight is a straight line parallel to the road. Example 4: Locus of the moving end of the minute hand of a clock is a circle. Part 2: Locus and its Constructions Explain the importance of constructions in geometric problems. Construction 1: Locus of points equidistant from two fixed points (perpendicular bisector). Demonstrate the construction process. Construction 2: Locus of points equidistant from two intersecting lines (angle bisector). Demonstrate the construction process. Part 3: Problem-Solving Work through specific problems from Selina's exercises, such as: Finding a point equidistant from two sides of a triangle and a vertex. Constructing triangles based on given conditions related to loci. Show how to apply the concepts of locus to solve real-world and geometric problems.
