Detailed explanation-1: -Geometrical isomerism is also called cis−trans isomerism and Tetrahedral complexes do not show geometrical isomerism because the relative position of the atoms with respect to each other will be the same. So Assertion is true but reason is false.

Detailed explanation-2: -The terms cis and trans are from Latin, in which cis means “on this side” and trans means “on the other side” or” across". The term” geometric isomerism” is considered as an obsolete synonym of “cis/trans isomerism” by IUPAC.

Detailed explanation-3: -Cis and trans isomers are types of geometric isomers, where the functional group is placed differently with regards to the double bond. In general, a cis isomer has molecules on one side of the double bond. A trans isomer has molecules on the other side of the double bond.

Detailed explanation-4: -Geometric Isomers. Geometric isomers are two or more coordination compounds which contain the same number and types of atoms, and bonds (i.e., the connectivity between atoms is the same), but which have different spatial arrangements of the atoms. Not all coordination compounds have geometric isomers.
