1. Given the vertices of the triangle ABC: A (x1, y1), B (x2, y2), C (x3, y3). Search:
  a) side of the equation AB
  b) the height of the equation CH
  c) The median equation AM
  d) the point of intersection of the median N AM and height CH
  e) The equation of the line passing through the top with parallel sides AB
  e) the distance from the point C to the line AB

  1.12 A (-4, 2) B (8, -6) C (2, 6)

2. Solve the following problems.
  2.12 Known side of the equation AB triangle ABC 4x + y = 12, the height BH 5x - 4y = 12 and AM x + y = 6. Find the equation of the other two sides of the triangle ABC.
