Question No.2 (iii)
Q.2. In the triangle A(8,6), B(-4,2), C(-2,-6), find the slope of:
(i) Each side of the triangle
(ii) Each median of the triangle
(iii) Each altitude of the triangle
Q. How to check that two lines are parallel to each other?
If slope of one line is equal to the slope of the other line then the lines will be parallel.
Q. How to check that two lines are perpendicular to each other?
If slope of one line is negative reciprocal of the slope of the other line then lines will be perpendicular.
