A Triangle :)
Segments.
whatto line segments intersect but are not perpendicular
No. Line segments end at the endpoints.
No
what of a triangle has three line segments that intersect only at their endpoints
triangel
A polygon.
A Triangle :)
If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
Segments.
whatto line segments intersect but are not perpendicular
Line segments that do not intersect are parallel lines
If each segment intersects exactly two other segment but could, if extended, intersect the third, then the figure is a quadrilateral. Otherwise it is a parallelogram.
Yes. Parallel Lines are also two coplanar lines that do not intersect.
All line segments have exactly two endpoints.
