Answer: <most likely answer, as short as possible; not a complete sentence, just the answer!>.

The problem is: right triangle pqr is to be constructed in the xy - plane so that the right angle is at p and pr is parallel to the x - axis . the x - and y - coordinates of p , q , and r are to be integers that satisfy the inequalities - 4 < = x < = 5 and 6 < = y < = 16 . how many different triangles with these properties could be constructed ?
100
It is not possible to determine the exact number of different triangles without additional information. However, we can find a lower bound by considering the number of
