E-Math Note : Congruency Triangle Tests

I was rather unwilling to talk about this topic previously as I remembered I didn't quite like triangles LOL ( Lame excuse!). Well, things usually turned out the more challenging something is, the more when one avoids, the worse thing get. In Singlish, we called it "Jia Lat" aka 1 Difficult, troublesome. 2 Severe, to a great extent; transf. very bad, terrible." Adopted from singlishdictionary.com

I finally took the "courage" to face this demon & guessed what! I conquered it within 30 minutes using sheer eye power! Read on for a 3 minutes summary on this topic [Read more...] about E-Math Note : Congruency Triangle Tests

E-Maths Note: Quadratic Equations & Graphs Series

For those in Sec 3s, you will be learning more about Quadratic Graphs. Not so much of the drawing like in Sec 2s, but more of indepth understanding.

A quadratic graph typically is either a smiley face :) or a sad face :( some prefer to call them U or n shape.

Q1: Do you know how to tell the "mood" of the quadratic graph given its equation? Be very speific to ensure crystal clear understanding.

Eg :) or :(
