In this chapter, we will be learning about loci in two dimensions. We will start by understanding what a locus is and how it relates to real-life situations. We will then explore different types of loci, such as points that are a constant distance from a fixed point, points that are equidistant from two fixed points, points that are a constant distance from a straight line, points that are equidistant from two parallel lines, and points that are equidistant from two intersecting lines. We will also learn how to construct these loci.
• Recognise loci in real life situations and hence explain the meaning of locus
• Describe the locus of points that are of (i) constant distance from a fixed point, (ii) equidistant from two fixed points, (iii) constant distance from a straight line, (iv) equidistant from two parallel lines, and (v) equidistant from two intersecting lines, and hence construct the locus
• Determine the locus that satisfies two or more conditions
• Solve problems involving loci
