Locus
Loci is a very important part of the syllabus and contributes much to your final exam score.
Many people who try to avoid this topic eventually miss an A. Its considered a score booster.
In this post, I will explain few tips on the topic that were discovered from previous examinations
1. Two main angle-constructions.
Loci is centered on two main angles which are 90° and 60°. Candidates must be accurate in constructing these angles since all angles are built upon these principles.
Angles that uses the principles are 120°, 135°, 150°, 45°, 30° to name a few.
#2 Shapes.
Candidates must be familiar with properties if different shapes like Kite, Parallelogram, rhombus, Trapezium and Triangles.
Zimsec complicates these questions by introducing unpopular shapes into a loci question.
#3 Bearing
Loci can be tested using bearing principles but the constructions are based on two main angles we discussed before.
The major tip here is to remember that bearing is measured from the North in case of a three-figure bearing
#4 Using compasses for shape completion
At times the loci question can provide an angle and all dimensions of a shape.
In this case they will be testing your ability to use compasses to complete a shape.
#5 Bisecting
Loci questions test bisection of lines and angles
#6 Distance from a point/Line.
You can be tested construct locus of points from a given point, say A. You must be able to construct a circle with that point as the center.
You must also be able to construct parallel lines if locus of points distant from a line is tested.
#7 Label your work.
Many candidates forget to label their constructions , dimensions and points. It is imperative to label all your work..
These are some of the few tips on this topic.
NB: There are videos which cover all 10 tips in the topic. If you are interested Contact the tutor on WhatsApp +263733796118.
