The vertices of the triangle are points A (1; 1) B (0; 3) C (-1; -1) determine the coordinates AB, BC, CA

We find the necessary coordinates according to the rule for finding the coordinates of vectors. To find the coordinates of the vectors, you need to find the difference between the corresponding coordinates of the end and start points.
AB = (0 – 1; 3 – 1) = (-1; 2);
BC = (-1 – 0; -1 -3) = (-1; -4);
CA = (1 – (-1); 1 – (-1)) = (1 + 1; 1 + 1) = (2; 2).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
