The molecule SO2 is having two sigma bond pairs and lone pair, hence, it exhibits angular or V-shape structure. The molecule H2O is having two sigma bond pairs and a lone pair hence, it exhibits angular or V-shape structure. So, both molecules are having same shape. But double bond-double bond repulsions are greater than single bond repulsions, hence, the bond angle in sulphur dioxide is greater than water.

SO2 and H2O both have V-Shape
Bond angle: SO2>H2O
