only 1 lines can contain 3 collinear points. Maybe you mean coplanar?
It is a polygon that is a closed plane figure with 3 or more straight lines.
Oh, dude, let me break it down for you. So, if you draw three lines in a circle, you can definitely create eight pieces. Each line you draw cuts the circle into two parts, so with three lines, you'll have eight pieces in total. It's like slicing a pizza, but with geometry.

In 2 dimensions, a polygon. In 3 dimensions, a polyhedron.
3 lines and one plane

If the shape has three straight lines and no other lines then it has to be a triangle
skew, parallel, intersecting.
A scalene triangle.
A straight angle is 180°, so if there is 180° between the first line and the second, and 180° between the second and the third, then the result is a straight line.
There are two classification A. Straight lines 1.Horizontal lines - these are straight lines in lying position and they suggest calmness. 2. Vertical lines - these are straight lines in upward position and they suggest height and power. 3. Zigzag lines - these are straight lines, too. They suggest disorderliness and trouble. 4. Slanting lines - these are straight lines that give the feeling of action or motion. B.Curved Lines - lines that suggest meanings like motion and feelings. 1. Wavy lines - these lines suggest gracefulness or continuity. 2. Spiral - these are curved lines that suggest action and motion. 3. Concave - a line curved inward. 4. Convex - a line curved outward.
