Step 1: Construct the triangle ABC.

First, we need to draw the triangle ABC with vertices A, B, and C.

Step 2: Construct the midpoint of BC.

To find the midpoint of BC, we can use the midpoint formula. The midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates ((x1 + x2) / 2, (y1 + y2) / 2). In this case, M is the midpoint of BC, so we can find its coordinates by averaging the x and y coordinates of B and C.

Step 3: Construct the point K on AB.

Now, we need to find a point K on AB such that AK = KM. Since KM = MC, this means that AK = MC. To find this point, we can use the concept of similar triangles. If we can construct a point K on AB such that triangle AKM is similar to triangle CKM, then AK = MC.

Step 4: Find the ratio of AM to MC.

To make the triangles similar, we need to find the ratio of AM to MC. Since M is the midpoint of BC, AM = MC/2. Therefore, the ratio of AM to MC is 1/2.

Step 5: Construct the point K using the ratio.

Now, we can use the ratio to find the point K. Since AM = MC/2, we can find K by going half the distance from A to M along the line segment AM. In other words, K is the point on AM such that AK = AM/2.

Step 6: Verify the construction.

We can verify our construction by checking that AK = KM = MC. Since AK = AM/2 and AM = MC/2, we have AK = MC/4. Also, KM = MC/2. Therefore, AK = KM = MC/4, which is not equal to the given condition AK = KM = MC.

Conclusion: It is not possible to construct the point K on AB and the point M on BC such that AK = KM = MC using only a straightedge and compass.
