Solution. We prove the rst part. The intersection of two convex sets is convex. There-fore if Sis a convex set, the intersection of Swith a line is convex. Conversely, suppose the intersection of Swith any line is convex. Take any two distinct points x1 and x2 2 S. The intersection of Swith the line through x1 and x2 is convex.

There are a number of solutions to this .

Name each polygon by its number of sides. Then classify it as convex or concave and regular or irregular . 62/87,21 The polygon has 3 sides, so it is a triangle. None of the lines containing the sides have points in the interior of the polygon. So, the polygon is convex. (All triangles are convex.)File Size: 1MB
