1. Given two end points on a line (10, 15) and (13, 13), find the points between these two end points. 2. Given a circle with a center point of (0, 0) and radius of 5, what are the points in the first octant? 3. Given an ellipse with a center point of (0, 0) and major axis of 5 and minor axis of 2, what are the points in the first quadrant? 4. What is the difference between a concave polygon and a convex polygon in terms of a line segment placed inside of the polygon? 5. One edge of a polygon has a vertex points (100, 200) and (500, 700), what is the intersection point for a scan line of y = 250?

Solution

4) convex polygon : All line segments which are placed inside of the polygon, all points on the line segments are also interior points of the polygon then it is called convex polygon

concave polygon : All line segments which are placed inside of the polygon,some points on the some line segments are if exterior points of the polygon then it is called concave polygon
