- Create the equation of the median and the height From A where ABC is a triangle, find the angle between median and the height from A.
$$A(2, 0); B(1, -2), C(3, 6)$$
Solution:
If M is the middle point between A and C it has cordinates M(2, 2). The equation of the median can be found with:
$$(x-M1)/(M1-A1) = (y-M2)/(M2-A2)$$ $$0y=2x-4$$
How can I get the height AH ?
- Create the equation of the sides of a triangle ABC if it's given B(1, -2) and the height h: x + 4y -2 =0 and the median *m : x = 2 *. h is the height which comes from B, m is median which comes from B:

How do we solve this one ?
- make a equation of the plain a containing
$$l1: x = λ +3; y = −λ; z = λ$$ $$l2 : x = µ +1; y = −µ; z = µ +4$$
and find the projection of the line $$l:x = 2t+1; y = t +1 ; z = 3t+1$$ on a
