3. Draw the altitude for the triangle shown.

Answers:

1. Every triangle has three altitudes. For an obtuse triangle, at least one of the altitudes will be outside of the triangle,
   as shown in the picture at the beginning of this concept.


2. The triangle is an acute triangle, so the altitude is inside the triangle as shown below so that it is perpendicular to
   the base.


3. The triangle is a right triangle, so the altitude is already drawn. The altitude isX Z.
