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.
3 altitudes.
Yes, except that with a right angled triangle, two of the altitudes will also be the sides of the triangle.
A triangle has three altitudes.
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.
Draw two altitudes: an altitude is a straight line from a vertex to the opposite side. The three altitudes of a triangle meet at the orthocentre, but two are enough to determine the point.

3 altitudes.
draw a triangle ABC and three altitudes AH BL and CM AH_|_ BC BL _|_AC and CM _|_ AB for right triangle AHB, using Pythagorean AH² = AB² - BH² so AH < AB similarly for other altitudes thus AH+BL+CM is < AB+BC+CA
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.
