answer with explanation:

it is given that ,

  δ mno ≅ δ xyz

when two triangles are congruent,then their corresponding parts, that is their corresponding angles and corresponding sides are congruent.

1.⇒ corresponding angles

  ∠m= ∠ x

  ∠n = ∠y

  ∠ o = ∠ z

2. corresponding sides

  mn = x y

  no = y z

  mo = x z
