In any triangle ABC, with sides a = BC, b = CA and c = BA, then prove that a = b cos C + c cos B, b = c cos A + a cos C, c = a cos B + b cos..

The C-C bond is viewed end on. A point represents the near carbon and three lines radiating from this point represent the bonds linking the three other groups attached to this carbon. A circle represents the other carbon atom that is far away and the three bonds attached to this carbon atom are re..

The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon). The horizontal lines indicate bonds directed towards the reader. The vertical lines indicate bonds directed away from the reader. By rotating through an angle of 180 o within the plan..
