Focus On Locus

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.

5 people who can make you fail or Hate Mathematics.

5 People who can make you fail Mathematics

Mathematics is a unique subject. It needs great attention, higher level of understanding, sharp memory and concentration during learning or a study. Miss a lesson and it will torment you all the days of your live. You can be motivated by your environment and people who hang around with you.

However, they are people who can distract your concentration in mathematics. They will try to convince you that they are more intelligent than you, and if they are not successful in the subject, you will also definitely fail. Someone actions will also discourage you from following recommended path to be successful in the subject.

Let's briefly analyze them

 

1. Your Teacher

A teacher contributes at least 50% to your success in any subject. The remainder is attributed to hardworking, source of information, attitude towards the subject and exam skills. If a teacher discourage you and also claim you are going to fail the subject, it's highly likely you will fail the exam. 

A teacher can simply avoid helping you, or letting you know the source of your errors. Many teachers selects students to concentrate with, and leave the rest to fail. Other teachers believe it's a waste of effort to coach slow learners and below average performers

2. Your Classmate/Schoolmate

Classmates or schoolmates who are challenged by any subject will try to incite others to also hate the subject. They will even statistically prove to you that many students from your school fail the subject and concentrating on it is just a worst of time. This can change your philosophy towards the subject and eventually result in a failure

3. Your Parent, Brother or Sister

When a child fails or succeeds in school, parents and family members try to justify it by now they performed in school. Others will even blame each other for the failure of their children. They believe intelligence is a genetical. You can be discouraged from mathematics through their beliefs and justifications. 

4. A candidate  next to you in an Exam

Actions of other candidates in an Exam room can affect your performance. At times, it's wise to ignore whatever is happening in an exam and concentrate on your work. Before e-marking was widely adopted, candidates used to write on sheets of paper. You would see others raising their hands for more answer sheets and submitting a booklet of answers, when you have just answered in only 3 or 5 sheets. Others would request graph paper but you haven't located questions that required a graph. 

You can spoil your work by trying to expand what you have already written. Fresh minds have best answers. By trying to revise what have been answered by fresh minds when tired will only guarantee you failure. 

5. Your FRIEND

Friendship is a result of something in common. True friends will try to match their characters and attitudes in everything. Even in the classroom, they will behave the same.if your friend hates the subject, you will eventually buy into it. Friends are greatest threats to our abilities.
