The answer depends on what the triangle is intersecting.
They are not. The perpendicular bisectors of a triangle, for example, intersect at the orthocentre of the triangle. So perpendicular lines can be intersecting and conversely.
3 intersecting lines, because none of the three points are right angles.

No. Intersecting lines could be only two of them - which are not enough to form a triangle.

A triangle has by definition three intersecting sides. If two of the sides are parallel, they will never intersect, so no triangle can ever be formed.
The three lines making up a triangle do not intersect (cross) each other. Two lines join at each corner of the triangle.
No. Circumvention means to surround or to go around or bypass. It is not a geometric term and has nothing to do with a triangle. Having said that, a circle can be drawn from the circumcentre of any triangle so that it passes through the vertices of the triangle.
This is a description of a scalene triangle.
The prefix 'tri' mean three or triple. An angle is formed when two lines intersect. A triangle is therefore a plane figure where three enclosed angles are formed by intersecting lines.
No, it can be a triangle intersecting a set of three faces which meet at one vertex.
