Answer:

Therefore,

m∠D = 44°

Explanation:

Given:

ΔABC ≅ ΔDBC

AB = 10

m∠A = 44°

To Find:

m∠D = ?

Solution:

ΔABC ≅ ΔDBC ............Given:

If two triangles are congruent then the corresponding parts of congruent triangles are congruent. Also known as CPCTC.

∠A ≅ ∠D .............CPCTC

But m∠A = 44° ........Given:

Transitive Property :

If a = b ;

a = c ; then by Transitive Property we have

b = c

∴ m∠D = 44° ............Transitive Property
