As shown above, I've drawn a right triangle with a hypotenuse of 10. However, I could not figure out the altitude (as shown in the dotted lines).
Which of the following could be the altitude in question?

The locus of right angles of all possible right triangles with a given hypotenuse is a semicircle with the same diameter, since the angle inscribed in a semicircle is always a right angle. Therefore, the different altitudes of a right triangle with a hypotenuse of 1 0 will correspond with the different heights of the semicircle with a diameter of 1 0 , which would be 0 < x ≤ 5 .
This means that out of the options given, 3 , 4 , and 5 are possible altitudes, but not 6 .
