  2. Describe the difference between a Convex Polygon and a Concave Polygon. Please be sure to include examples with your answers. • Convex: • Has ALL of its interior angles less than 180 • ALL vertices point OUTWARD • NO “sunk-in” places • In a convex polygon if A and B are any two interior points, they can be connected • by a line segment which does not go outside of the polygon • Concave: • Has one or more internal angle greater than 180 • Has at least one “caved-in” or “sunk-in” places • Has at least one vertex point INWARD • In a concave polygon if A and B are any two interior points, they can be • connected by a line segment which goes outside of the polygon

  3. Concave Polygons Convex Polygons

  4. What is another way of finding the measure of the exterior angle??
