Let (0, 0) divide (3, 5) and (−3, −5) internally in the ratio k:1. According to the question,3 - 3k = 0 3k = 3 k = 1 Hence, the origin divides (3, 5) and (−3, −5) internally in the ratio 1:1.

According to the question, Vertices of the triangle are (0, 0), (3, 0) and (4, 6). 

Let one of the vertices of the triangle be (a, b). According to the question, and a - 3 = 12 a = 15

b - 2 = 15 b = 17 The remaining vertex is (15, 17).
