a) the equation of the side AB
b) the equation of height CH
c) the equation of the median AM
d) the point N of the intersection of the median AM and the height CH
e) equation of a straight line passing through vertex C parallel to side AB
f) distance from point C to line AB
1.20 A (−7, −2) B (−7, 4) C (5, −5)
2. Solve the following tasks.
2.20 The equations of the sides of a quadrangle are given: x - y = 0, x + 3y = 0, x - y - 4 = 0, 3x + y - 12 = 0. Find the equations of its diagonals.
