Question

Orthocenter and circumcenter of a ΔABC are (2, 3) and ( 6, 8), respectively. If the coordinates of the vertex A are (6 ,8 ), then find the coordinates of the middle point of BC.

Answer 1

Answer:

A triangle has its three sides equal to a , b and c . If the coordinates of its vertices are A(x_1, y_1),B(x_2,y_2)a n dC(x_3,y_3), show that |[x_1,y_1, 2],[x_2,y_2, 2],[x_3,y_3, 2]|^2=(a+b+c)(b+c-a)(c+a-b)(a+b-c)
