3 altitudes.
A triangle has three altitudes.
no; a triangle must have an obtuse angle if one of its altitudes is outside of the triangle, and in this case 2 of the altitudes are out of the triangle.
Yes, except that with a right angled triangle, two of the altitudes will also be the sides of the triangle.
A triangle only has one altitude which is its perpendicular height.
No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.

All triangles have three altitudes.
Yes, except that with a right angled triangle, two of the altitudes will also be the sides of the triangle.
the point of concurrency of the altitudes of a triangle is called the orthocenter.

Obtuse Triangle
A triangle only has one altitude which is its perpendicular height.
No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.
In an equilateral triangle, there are three altitudes, each of which is perpendicular to the side of the triangle it intersects. These altitudes are the lines that connect a vertex to the opposite side at a right angle. Additionally, the three medians of the triangle also intersect at the centroid, but they are not perpendicular to the sides. Therefore, the main perpendicular lines to consider are the three altitudes.
