☑ Learn how to answer questions on construction and loci in Wassce exams
☑ Learn by watching short videos and working through the examples.
This course will help you understand the main concepts involved in the construction and loci sections of the Wassce core maths exam. It will explain what a locus is, how to bisect and angle, how bisect a line and how to combine this knowledge to construct triangles and quadrilaterals.
Topics covered include:
Bisector of angles
Bisector of a line
Angles of 90, 60, etc
Points at a given distance from a given point.
Points equidistant from two given points.
Points at a given distance from two straight lines.
Construction of triangles and quadrilaterals
To be able to do this course, you must have a working knowledge of angles, triangles and quadrilaterals as it is assumed that you have already encountered these topics earlier on. You must also be confident in using a mathematical set. Also, always have a sharp pencil and an eraser to hand.
The best way to get the most out of this course is to spend time working out how you would answer the question yourself, before looking up our own suggested steps. Please make sure that you pause the video after we have explained what needs to be done.
Construction and loci are one of the more difficult sections of the Wassce exam and quite a few candidates avoid it. However, if you plan to study an engineering and/or science subject later on, we would advise you to take this course.
