The missing measures in the given triangles are,

BN = 9 cm

TW = 14 cm

BF = 12 cm

m ∠W = 82°

m ∠B = 67°

m ∠F = 31°

What is isomorphic triangles?

The triangulations of two simple polygons, Tp and Tq, are referred to as isomorphic (or occasionally compatible) if an isomorphism exists between the vertices of P and Q, and the isomorphism has the property that three vertices of P form a triangle in Tp if and only if the mapping of the three vertices in Q also form a triangle in Tq.

Given: ΔSTW ≅ ΔBFN

We have to find the missing measure.

As the triangles are isomorphic.

⇒ All sides and angles of two triangles are same.

⇒ ST ≅ BF, TW ≅ FN, SW ≅ BN

∠S ≅∠B, ∠T ≅ ∠F, ∠W ≅ ∠N

As SW = 9 cm ⇒ BN = 9 cm

As FN = 14 cm ⇒ TW = 14 cm

As ST = 12 cm ⇒ BF = 12 cm

As m ∠N = 82° ⇒ m ∠W = 82°

As m ∠S = 67° ⇒ m ∠B = 67°

Now m ∠F = 180° - 67° - 82°

⇒ m ∠F = 31°

Hence, the missing measures in the given triangles are,

BN = 9 cm

TW = 14 cm

BF = 12 cm

m ∠W = 82°

m ∠B = 67°

m ∠F = 31°
