Answer 1

$\huge\boxed{Answer}$

A triangle can have 3 altitudes.

The altitude is a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a right, or 90-degree, angle. The opposite side is called the base. All triangles have three vertices and three opposite sides.
