Question

question 5 of 10 which of the following are exterior angles? check all that apply. a. ∠2 b. ∠5 c. ∠4 d. ∠6 e. ∠1 f. ∠3

Explanation:

Step1: Recall exterior - angle definition

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

Step2: Analyze each angle

• $\angle1$ is an interior angle of the triangle.
• $\angle2$ is formed by one side of the triangle and the extension of an adjacent side, so it is an exterior - angle.
• $\angle3$ is formed by one side of the triangle and the extension of an adjacent side, so it is an exterior - angle.
• $\angle4$ is formed by one side of the triangle and the extension of an adjacent side, so it is an exterior - angle.
• $\angle5$ is formed by one side of the triangle and the extension of an adjacent side, so it is an exterior - angle.
• $\angle6$ is an interior angle of the triangle.

Answer:

A. $\angle2$, B. $\angle5$, C. $\angle4$, F. $\angle3$
