To find the ordered pairs of the midpoints of the medians of the triangle given points A, B, and C, we first need to ascertain the coordinates of the triangle vertices:

A = (4, 5)
B = (1, 2)
C = (6, 2)

Next, we need to find the midpoints of the sides of the triangle since the medians connect the vertices of the triangle to the midpoints of the opposite sides.

Step 1: Calculate the Midpoints

Midpoint of BC (between points B and C): \[ M_{BC} = \left(\frac{x_B + x_C}{2}, \frac{y_B + y_C}{2}\right) = \left(\frac{1 + 6}{2}, \frac{2 + 2}{2}\right) = (3.5, 2) \]
Midpoint of AC (between points A and C): \[ M_{AC} = \left(\frac{x_A + x_C}{2}, \frac{y_A + y_C}{2}\right) = \left(\frac{4 + 6}{2}, \frac{5 + 2}{2}\right) = (5, 3.5) \]
Midpoint of AB (between points A and B): \[ M_{AB} = \left(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2}\right) = \left(\frac{4 + 1}{2}, \frac{5 + 2}{2}\right) = (2.5, 3.5) \]

Step 2: Identify the Medians

Now we can determine the ordered pairs for the three medians:

Median from A to M_{BC}: A to (3.5, 2)
Median from B to M_{AC}: B to (5, 3.5)
Median from C to M_{AB}: C to (2.5, 3.5)

This gives us the pairs:

For A: (4, 5) to (3.5, 2)
For B: (1, 2) to (5, 3.5)
For C: (6, 2) to (2.5, 3.5)

Conclusion

The ordered pairs of the medians bisectors based on the midpoints calculated (M_{AB}, M_{AC}, M_{BC}) are:

M_{BC} = (3.5, 2)
M_{AC} = (5, 3.5)
M_{AB} = (2.5, 3.5)

However, let's align with the responses given in your options. It seems like the A, B, C coordinates mentioned (4,5), (1,2), and (6,2) relate to the initial triangle vertex points rather than the medians' midpoints. Given the coordinates, I would match them as follows with what you asked:

none of the provided options seem to correspond directly to the correct calculated midpoints of the triangle's sides or medians.

If you are looking for the specific medians to the associated midpoints with multiple choice options, those are necessary to evaluate which options could align if they were provided in the text.

I apologize for the confusion earlier. Let's start from the triangle vertices and find the medians' midpoints directly.

Given the vertices of the triangle:

A = (4, 5)
B = (1, 2)
C = (6, 2)

We need to identify the midpoints of the opposite sides to establish the coordinates of the medians.

Finding Midpoints

Midpoint of BC: \[ M_{BC} = \left(\frac{x_B + x_C}{2}, \frac{y_B + y_C}{2}\right) = \left(\frac{1 + 6}{2}, \frac{2 + 2}{2}\right) = (3.5, 2) \]
Midpoint of AC: \[ M_{AC} = \left(\frac{x_A + x_C}{2}, \frac{y_A + y_C}{2}\right) = \left(\frac{4 + 6}{2}, \frac{5 + 2}{2}\right) = (5, 3.5) \]
Midpoint of AB: \[ M_{AB} = \left(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2}\right) = \left(\frac{4 + 1}{2}, \frac{5 + 2}{2}\right) = (2.5, 3.5) \]

Summary of Midpoints (Medians' Endpoints)

Median from A to midpoint of BC: (4, 5) to (3.5, 2)
Median from B to midpoint of AC: (1, 2) to (5, 3.5)
Median from C to midpoint of AB: (6, 2) to (2.5, 3.5)

Ordered Pairs for Midpoints of Each Median:

To match with your options from the list you shared:

Midpoint of BC: (3.5, 2)
Midpoint of AC: (5, 3.5)
Midpoint of AB: (2.5, 3.5)

Correct Answer Set Based on Given Options

Based on your options:

Options seem to reference other labels that don't match our calculated midpoints.

However, if we examine your original sets:

Looking at (1, 2), (5, 3.5), and (2.5, 3.5) also doesn’t perfectly align.

Thus indicating none were sufficient to encapsulate both correctly:

Final pairs you may want to choose aligning with original points could be:

\(0C = (3.5, 2)\) (which is the midpoint to point B)
\(b =(5, 3.5)\) (this captures the midpoint of AC relationship)
And then as a closest varied aspect alongside could be \(\text{(2.5, 3.5)}\)

In conclusion, the likely match from available options without conflicting will remain external to what equated to our derived medians directly but gives a structural insight with further exploration into geometry structuring required.

If you could specify or clarify just which selection option corresponds most directly or any further criteria required, it would help assist in pinpointing even more precisely. Please advise if there’s anything specific you want me to focus on.
