image of a triangle with angles labeled 1,2,3,4,5,6
a. ∠2
b. ∠4
c. ∠1
d. ∠6
e. ∠3
f. ∠5

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, lying outside the triangle.

Step2: Analyze Each Angle

• ∠1: Inside the triangle (interior angle).
• ∠2: Formed by extending a side, outside the triangle (exterior angle).
• ∠3: Formed by extending a side, outside the triangle.
• ∠4: Formed by extending a side, outside the triangle.
• ∠5: Inside the triangle (interior angle, adjacent to ∠3/∠4).
• ∠6: Inside the triangle (interior angle).

Answer:

A. ∠2, B. ∠4, E. ∠3
