1. The document provides instructions for determining the extreme points of a triangle given its vertex points.
2. The method involves placing the vertex points on a coordinate grid, connecting the points to form the triangle, and then calculating the x- and y-coordinates of each vertex using the distances from the origin.
3. The extreme points are identified as the vertex points with the maximum and minimum x- and y-coordinates, and the calculations are verified using the distances obtained from the origin.
