Answer 1

Step 1: Draw the three medians of the triangle. Draw each median so that it starts at a vertex and ends at the midpoint of the opposite side.

Step 2: Find the coordinates of each midpoint by taking the sum of the x-coordinates and dividing by 2 and taking the sum of the y-coordinates and dividing by 2.

The midpoint between (0, 0) and (b, c) is ((0+b)/2, (0+c)/2) = (b/2, c/2). The midpoint of (0, 0) and (a, 0) is ((0+a)/2, (0+0)/2) = (a/2, 0). The midpoint of (a, 0) and (b, c) is ((a+b)/2, (0+c)/2) = (a+b/2, c/2).

Step 3: Find the coordinates of P, the point where the medians appear to intersect, on each median. Use the formula (vertex coordinate + 2 * midpoint coordinate)/3.

Step 4: Find the coordinates of P on the median that starts at vertex (0, 0) and ends at midpoint (a+b/2, c/2).

(1/3)(0, 0) + (2/3)(a+b/2, c/2) = (a/3 + 2(a+b)/6, c/3 + 2c/6) = ((2a/6 + 2b/6), (c/3 + c/3)) = ((a+b)/3, 2c/3).

Find the coordinates of P on the median that starts at vertex (a, 0) and ends at midpoint (b/2, c/2).

(1/3)(a, 0) + (2/3)(b/2, c/2) = (a/3 + 2b/6, 0/3 + 2c/6) = ((2a/6 + 2b/6), 2c/6) = ((a+b)/3, c/3).

Find the coordinates of P on the median that starts at vertex (b, c) and ends at midpoint (a/2, 0).

(1/3)(b, c) + (2/3)(a/2, 0) = (b/3 + a/3, c/3 + 0/3) = ((b+a)/3, c/3).

Step 5: The coordinates of P on each median are ((a+b)/3, 2c/3), ((a+b)/3, c/3), and ((b+a)/3, c/3), which proves that the three medians of this generic triangle all intersect at the same point.
