This is what I have in mind.

PE is congruent to EO because a rhombus has consecutive sides that are congrunet

<SPE and <VOE are congruent by the subtraction rule since <SPR and <VOR are congruent-and those angles include <EPR and <EOR which are congruent because a rhombus has opposite sides that are congruent. SO you just subtract the <EPR and <EOR from the <SPR and <VOR and you get <SPE and <VOE-whom are congruent.

This one I'm not sure about...<VEO and <SEP are congruent beacsue vertical lines are congruent.

And therefore triangles SEP and VEO are congruent because of <AAS is congruent to <AAS

And finally I could say ES is congruent to VE beacuse congruent parts of congreunt triangles are congruent.

Correct? Please make sure that it is 100% correct
