b. ∠6
c. ∠3
d. ∠1
e. ∠2
f. ∠4

Explanation:

Step1: Recall Exterior Angle Definition

An exterior angle of a triangle is formed by one side of the triangle and the extension of an adjacent side. It is supplementary to the adjacent interior angle.

Step2: Analyze Each Angle

• ∠5: Interior angle (inside the triangle).
• ∠6: Formed by extending a side, supplementary to ∠5 (interior), so exterior.
• ∠3: Formed by a side and an extension, supplementary to ∠2 (interior), so exterior.
• ∠1: Interior angle (inside the triangle).
• ∠2: Interior angle (inside the triangle).
• ∠4: Formed by extending a side, supplementary to ∠5 (interior), so exterior.

Answer:

B. ∠6, C. ∠3, F. ∠4
