As we have learnt, 

Epimers are isomers that differ in configuration at one of the asymmetric / chiral centre.

Glucose and Mannose are C-2 epimers as represented below 

D - mannose                                D-glucose 

                              

Note: Other epimers of Glucose include Allose (C-3) and Galactose (C-4)
