1. The problem is to generate an image showing the three different altitudes of a triangle. 2. An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side. 3. To construct the altitudes, we drop perpendiculars from each vertex to the opposite side. 4. These altitudes intersect at a single point called the orthocenter. 5. Since the user requests an image, but no specific triangle or coordinates are given, we describe the altitudes generally. 6. The altitudes can be represented by lines perpendicular to each side passing through the opposite vertex. 7. The orthocenter is the common intersection point of these altitudes. Final answer: The three altitudes of a triangle are the perpendiculars from each vertex to the opposite side, intersecting at the orthocenter.
