Hi,         



using Picture on the left for illustration purposes:

Proving that the diagonals of a rhombus ABCD bisect the angles of the rhombus.



ABCD is a rhombus            |given

sides AB = BC = CD = DA      |Definition of a Rhombus

side AC = AC                 |Reflexive Property of congruence

ΔADC ≅ ΔABC                 |SSS Postulate

∠DAC = ∠BAC                |CPCTC

∠DCA = ∠BCA                |CPCTC 



Note: CPCTC: "Corresponding parts of congruent triangles are congruent"
