Question

the orthocentre of triangle abc with vertices (0,0),(3,1),(1,3)

Answer 1

let the given vertices of the triangle be A(0,0) , B(3,0) and C(0,4).



since AC and AB are perpendicular. therefore its ortho-centre is at A(0,0).

orthocentre is the intersection point of the altitudes from the vertices to the opposite sides.
