Question

slow that in a triangle median are concorrent​

Answer 1

Answer:

To prove that altitudes of a triangle are concurrent, we have to prove that the line segment joining the orthocentre and a vertex considering the altitudes drawn from the other two vertices of triangle meet at the orthocentre. ... We know that AD is perpendicular to BC, by the definition of an altitude of a triangle.

Step-by-step explanation:

Method 1 : (i) Solve any two equations of the straight lines and obtain their point of intersection. (ii) Plug the co-ordinates of the point of intersection in the third equation. (iv) If it is satisfied, the point lies on the third line and so the three straight lines are concurrent.
