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

• See below

Explanation:

Missing statement/reasons:

• 1. ABCD is rhombus
• 2. Definition of rhombus- all sides are equal
• 4. SSS (side-side-side) postulate
• 5. Corresponding parts of congruent triangles are congruent
