If an ABC triangle is transformed, the result will be triangle A'B'C'. In my country, A' is read as "A accent". However, when I saw this transformation video (Video: Transformations - Translation, Reflection, Dilation, and Rotation | Educational Video | WatchKnowLearn Educational Videos | WatchKnowLearn), they seem to pronounce A' as "A prime", "A point", "A prune", "A plum", whichever was right since I suck at English-listening. So, can you people tell me what exactly do they say how to pronounce A'?
