Express geometrical isomerism in

The compound(s) that exhibit(s) geometrical isomerism is (are)

True of False : All tetrahedral complexes show geometrical isomerism.

Why is geometrical isomerism not possible in tetrahedral compounds having two different types of unidentate ligands with the central metal ion ?

Is geometrical isomerism possible around triple bond ?

Assertion : Complexes of MX_6 and MX_5L type (X and L are unidentate) do not show geometrical isomerism. Reason : Geometrical isomerism is not shown be complexes of coordin-ation number 6.
