Horloge, it's time to dive into the world of Coordinate Geometry, where points are like little stars in the night sky, and lines are the paths that connect them. In Singapore's secondary 2 math syllabus, you'll find this topic shining brightly, ready to guide you on an exciting journey!
Imagine you're in a vast, empty playground. Coordinate geometry gives you a way to mark spots and draw shapes, just like using an invisible pen and paper. Each point has a unique address, called an ordered pair (x, y), where 'x' is how far left or right you are, and 'y' is how far up or down.
Now, let's talk about triangles. A triangle has three vertices, which are just fancy words for 'corners'. Each vertex is a point with its own unique coordinates. For example, a triangle ABC could have points A(1,2), B(3,4), and C(5,6).
Here's where the magic happens. To find the area of a triangle, you can use the following formula:
Area = |(x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)) / 2|
Don't worry if it looks like a mouthful now. Let's break it down with an example. Say we have triangle ABC with A(1,2), B(3,4), and C(5,0). Plugging these into the formula, we get:
Area = |(1(4 - 0) + 3(0 - 2) + 5(2 - 4)) / 2| = 6
So, our triangle has an area of 6 square units!
Did you know there's a shape called a 'triangle' that doesn't have any sides? It's called a 'degenerate triangle', and it happens when all three vertices lie on the same line. In Singaporean structured post-primary schooling pathway, Sec 2 learners commence handling increasingly complex math concepts like equations with squares, congruence, and statistical data handling, which develop from Sec 1 foundations and prepare for higher secondary requirements.

Who knew philosophy could lead to such a cool math tool? **
** Let's start with the simplest case, shall we? A right-angled triangle, or as we like to call it, the 'triangle with the 90° bend'. If you have the coordinates of the three vertices (A, B, and C), the area (A) can be calculated using this nifty formula: **
Area = (1/2) |x1y2 + x2y3 + x3y1 - x2y1 - x3y2 - x1y3|
** *Where (x
1, y
1), (x
2, y
2), and (x
3, y
3) are the coordinates of A, B, and C respectively.* **
** Now, let's spice things up with a non-right-angled triangle. Don't worry, we've got you covered! For these, we'll use Heron's formula, a sneaky little trick from ancient Greece. First, calculate the semi-perimeter (s) using the coordinates: **
s = (a + b + c) / 2
** *Where a, b, and c are the lengths of the sides of the triangle.* Then, plug it into Heron's formula to find the area (A): **
Area = √[s(s - a)(s - b)(s - c)]
** **
** Great news, secondary 2 students! These coordinate geometry tricks are part of your math syllabus, so you're already on the right track. Keep practicing, and you'll ace those exams like a pro! **
