∠ABC = ___?___
a) ∠MNP
b) ∠PMN
c) ∠ NPM
d) ∠NMP

Answer:
angle ABC = angle MNP
(See the single curved shape at angle B? Match it to the same one on the other triangle. The same with the double and triple angles. The marks in the middle of the lines work the same way. Lines BC, BA, NM, and NP are all the same length.)
Step-by-step explanation:
Answer:
The correct answer is option a) <MNP
Step-by-step explanation:
It is given a two congruent triangles.
ΔABC and ΔMNP
Corresponding parts of 2 triangles
1). Corresponding sides
AC = MP, AB = MN, and BC = PN
2). Corresponding angles
<ABC = <MNP , <BCA = <MPN and <BAC = <PMN
Therefore <ABC = <MNP
The correct answer is option a) <ABC = <MNP
