As can be seen in the picture, each carbon atom is doubly bonded to other carbon atom and is singly bonded to two Hydrogen atoms.
You must be knowing that only sigma bonds take part in determination of molecular shapes and not pi bonds, hence hybrization of each carbon atom will be of sp2 type.
A sp2 hybrization results in trigonal planer geometry and same is the case here.
Each C-H bonds are of equal length I.e. 108.7 pm and C=C bond is 133.9 pm long ( smaller than C-C single bond as pi bonds cause shortening of bond length).
Each H-C-H bond angle is around 117.3°.
This is smaller than trigonal planer angle of 120° because the pi cloud over C=C inserts a repulsion on bond pairs and hence contracts the ideal angles.
Hope this helps.
