Disclosed are a method for encoding/decoding an image and a recording medium storing a bitstream. A method of decoding an image includes: segmenting a higher coding block in an image into a plurality of coding blocks according to tree-based block segmentation; partitioning a current block into a first partition and a second partition based on geometric motion partitioning, the current block being one of the plurality of coded blocks; obtaining a first prediction block of the current block based on the motion information of the first division; obtaining a second prediction block of the current block based on the motion information of the second division; obtaining a final prediction block of the current block by performing a weighted sum of the first prediction block and the second prediction block; reconstructing the current block on the basis of the final prediction block, in which the geometric motion partitioning is performed on the basis of partitioning information indicating the direction of a partitioni
