What is the sum of the exterior angle measures, one at each vertex, of a convex decagon? square o

## Step 1<br />A convex decagon is a polygon with ten sides. The sum of the exterior angles of any convex polygon, regardless of the number of sides, is always 360 degrees. This is because when you walk around the polygon, turning through each exterior angle in turn, you make one full turn (360 degrees) at the end.<br /><br />## Step 2<br />In this case, the convex decagon has ten vertices, and each vertex has an exterior angle. However, the sum of these exterior angles will still be 360 degrees.
