Answer 1

• ABCD is Rhombus (Given)
• AD=BC=CD=BA( Sides of Rhombus are equal)
• DO=OB;AO=OC(Diagonals of parallelogram bisect each other
• ∆DOC$\cong$∆BOA(Side-Side-side congruence)
• <1$\cong$<2(As triangles are equal angles are also equal)

Answer 2

Answer:

• See below

Step-by-step explanation:

Missing statement/reasons:

• 1. ABCD is rhombus
