PROVE THE FOLLOWING THEOREM USING ANALYTIC PROVING. 1. The medians of a triangle are concurrent. •Let the vertices of the triangle be A(a, b), B(c,d), and C(e, f).

Show that the triangle with vertices  A(1, 2), B(−2, −1), and C(−4, 4)  is isosceles. We must first find the length of all three sides of the triangle by finding the distance between the vertices.   d(A,B) d(B,C) d(A,C) Therefore, the following conclusion can be reached
