1. The document describes algorithms for drawing lines, circles, and ellipses using a midpoint technique. It provides examples showing the steps and calculations for applying each algorithm. 2. Key steps of the line drawing algorithm include calculating slope, change in x and y, and a decision parameter to determine the next point. Circles use a decision parameter comparing radius to x and y values. Ellipses use two regions and decision parameters involving radii and x/y values. 3. Examples are provided applying each algorithm to draw specific geometric shapes given endpoint or radius values. Tables show the calculations and plotted points at each iteration.
