The bond angle referred to in chemical context is the angle formed between three atoms across at least 2 bonds when they are bonded together. For example, when water, H2O forms, it does not form in a linear fashion such as H-O-H, but rather in a bent, or "V" shape. The bond angle thus formed is 104.5º
