Question 251104
<font face="Garamond" size="+2">


I'm just guessing because your description isn't very clear, but I think your diagram is a kite shape with LV and OE as diagonals that intersect at X.  Proceeding on that assumption:


XV = XV Reflexive equality


angle OXV congruent angle EXV (both are right angles from given that LV perpendicular to OE)


OX = XE definition of mid-point


triangle OXV congruent to triangle EXV by SAS


OV congruent to VE by CPCT QED
