,><

Step-by-step explanation:

Answer 2

Answer:

Proof is stated below.

Step-by-step explanation:

Given: ABCD is a rhombus.

To Prove: <1 is congruent to <2.

Therefore,

Given: ABCD is a rhombus.

AD = BC = CD = BA: Definition of a parallelogram / rhombus ; four equal sides.

DO = OB ; AO = OC ; Diagonals of a parallelogram bisect each other.

Triangle DOC is congruent to BOA ; SAS (Side-Angle-Side) theorem.

<1 is congruent to <2 ; Definition of a parallelogram ; consecutive angles are supplementary.

Hence, proved.
