Answer 1

Answer:

Altitude can be outside the triangle

However, if one of the angles opposite the chosen vertex is obtuse, then it will lie outside the triangle, as below. The angle ACB is opposite the chosen vertex A, and is obtuse (greater than 90°). The altitude meets the extended base BC of the triangle at right angles.
