AA係咪一個condition?
2個三角形的2隻相對ge角一樣,最尾個隻角唔係都一樣咩?

更新1:

咁AAA咪多餘...?

更新2:

回frankyounghk: 簡單d黎講...我係想問prove similar triangle ge時候,可唔可以用AA而唔用AAA,因為我本書同老師都冇講AA係咪一個condition去prove similar triangle... sor..我表達能力唔太好...

✔ 最佳答案

係
因為三隻角加埋一定係180度
用三角形內角和就計到最尾隻角都係一樣

其實AA同AAA原理上係一樣不過未見過人用AA可以要統一掛,要用3個英文字母好似RHS,SSS,SAS都係三個英文三個英文字母

a triangle only has 3 angles. if 2 of the angles are equal, how come the third angle is not

equal. (180-a-b)=c

so AA is a condition for a similar triangle.
