Vectors is one of the newest and most challenging topics introduced in Sec 4 Mathematics, especially for students preparing for the O Levels. Unlike familiar topics such as algebra or geometry, vectors require students to combine different concepts together, including ratios, triangles, similar triangles and properties of shapes.
Many students struggle because they need to understand not only how to manipulate vector expressions, but also how to apply their knowledge of geometry. Questions involving trapeziums, points dividing line segments and area ratios often require students to recognise hidden relationships before solving the problem.
For example, consider this Sec 4 E Maths vectors question:
To solve questions like this, students need to combine their understanding of vectors with concepts such as similar triangles and the relationship between triangles with the same height. A strong foundation in these areas helps students approach unfamiliar O Level Mathematics questions with greater confidence.

- <div>hi</div>
- hiii
- I dont exactly understand this question
- the area of the triangle is 1/2 * base * height
- they are asking for the ratio of the areas
- notice how they have the same height
- for the 2 triangles
- I seeee
- means you just take the ratio of the bases
- which is 1 : 3
- ohhhhh
- thank youuuu
- np!
- byee
- byeee
