then find AMN.

Answer 1

Answer 2

i think it would be same because line joining to the mid points of the two sides of the triangle will be parallel to the third side so angle will be the same..

Answer 3

in triangle abc join M and N. now MN is parallel to BC and is equal to1/2BC. (midpoint theorem).
since MN is parallel to BC and AB is taken as a transversal.
angle abc= angle amn (corresponding angles)
therefore, amn= 80.
