Answer:
C. ∡3
A. ∡2
Step-by-step explanation:
From the diagram, the remote interior angles of ∡ 1 is ∡3 and ∡2
Prove
∡1 = ∡3 + ∡2
∡1 + ∡4 = 180° --- (1) (angles in a str. line)
In the triangle:
∡4 + ∡3 + ∡2 = 180° ( total angles in a triangle)
∡4 = 180 - ∡3 - ∡2 --- (2)
Substituting ∡4 = 180 - ∡3 - ∡2 into eqn (1)
∡1 + 180 - ∡3 - ∡2 = 180
∡1 = 180 - 180 + ∡3 + ∡2
∡1 = ∡3 + ∡2
Therefore, the remote interior angles are:
