1. A method of decoding an image performed by an image decoding apparatus, the method comprising:
reconstructing a first index for a first non-rectangular block within the current block and a second index for a second non-rectangular block within the current block, each of the first index and the second index being related to selection to a motion information candidate from among multiple motion information candidates; and
predicting the first non-rectangular block and the second non-rectangular block, based on the first index and the second index,
wherein motion information on the first non-rectangular block or the second non-rectangular block is determined to be L0 motion information which a motion information candidate corresponding to the first index or the second index has, in response to the first index or the second index being an even number index, and
wherein motion information on the first non-rectangular block or the second non-rectangular block is determined to be L1 motion information which the motion information candidate corresponding to the first index or the second index has, in response to the first index or the second index being an odd number index.
