Answer:

Explanation:

a) two

FACTS: Every triangle has 6 exterior angles, two at each vertex. Angles 1 through 6 are exterior angles. Notice that the "outside" angles that are "vertical" to the angles inside the triangle are NOT called exterior angles of a triangle.

b) 6 exterior angles

A triangle has 3 sides, 3 vertices, at these each vertices, we get 2 exterior angles, therefore, 3×2=6 exterior angles.
