對我黎講,有一個maths難題,就係關於deductive geometery...即演繹幾何..
我就係唔知第一步點寫..唔知從邊方面開始prove..教教我,thx!!
例如證明平行or證明a角=b角咁..應該點prove..
唔該各位maths精英!!

✔ 最佳答案
You 'll have to write what information(s) is/are given first.
From that GIVEN information(s), what conclusions have you found out.

here are some references:
corr.∠s, XX // YY
alt. ∠s, XX // YY
int. ∠s, XX // YY
~etc...

I'm not too sure if these can help you....sorry if they useless...
