最佳解答:
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 2008-02-14 20:47:54 補充: 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
其他解答:
Actually, I don't understand your question. Do you mind to explain?|||||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.
