Question 1185153: 1.The three straight lines y = x, 2y = 7x , and x + 4y - 60 = 0 form a triangle. Find the equations of the three medians, and calculate the coordinates of their point of intersection.
a. The points D(2, -3), E(-1, 7), F(3, 5) are the mid-points of the sides BC, CA, AB respectively of a triangle. Find the equations of its sides.
b. Prove that the points (1,−1), (-1, 1), (√3,√3) are the vertices of an equilateral triangle. Find the coordinates of the point of intersection of the medians of this triangle.
