noun, noun which may take the genitive case particle 'no'
same shape; isomorphism; same type; same pattern
Refers to things having the same form, shape, type, or pattern. In technical contexts, it can mean 'isomorphism' in mathematics, chemistry, or biology. The choice between 同形 and 同型 may reflect a nuance of physical shape vs. abstract type.

These two crystals have the same shape.
同形のパターンが繰り返されている。
The same pattern is repeated.
Compound of 同 (どう, 'same') and 形/型 (けい, 'shape'/'type'). The two kanji spellings reflect a nuance between physical form (形) and abstract type/model (型).
