Final answer:
To inscribe a rectangle in a 6-8-10 right triangle, options B and C are correct.
Step-by-step explanation:
To inscribe a rectangle in a 6-8-10 right triangle, we need to find the side of the rectangle that matches the length of one side of the triangle. Let's consider each option:
If one side of the rectangle is 4 cm, it cannot be inscribed in the 6-8-10 triangle because none of the sides of the triangle have a length of 4 cm.
If one side of the rectangle is 6 cm, it can be inscribed in the triangle by matching it with the 8 cm side of the triangle.
If one side of the rectangle is 8 cm, it can be inscribed in the triangle by matching it with the 6 cm side of the triangle.
If one side of the rectangle is 10 cm, it cannot be inscribed in the 6-8-10 triangle because none of the sides of the triangle have a length of 10 cm.
Therefore, options B and C are correct.
