Question

the diagram shows a convex polygon. what is the sum of the exterior angle measures, one at each vertex, of this polygon? °

Explanation:

Step1: Recall exterior angle rule

For any convex polygon (regardless of the number of sides), the sum of the measures of one exterior angle at each vertex is a constant value.

Step2: State the constant sum

The sum of exterior angles of any convex polygon is $360^\circ$.

Answer:

$360$
