Infinite lines can be drawn from a point
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
Lines parallel to the equator.
5 lines is symmetry
They are perpendicular lines
no
No, two electric field lines cannot originate from the same point because the electric field direction at that point would be ambiguous. Electric field lines always point in the direction of the electric field at a given point and represent the direction a positive test charge would move in that field.
Through two given lines, there can be either zero, one, or infinitely many lines that can be drawn, depending on their relationship. If the two lines are parallel, no line can pass through both. If they intersect, exactly one line can be drawn through their intersection point. If they are coincident (the same line), then infinitely many lines can be drawn through them.
This diagram is an example. The bolded lines are the lines you should draw._________ __________|/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||-----------|-------------|Note: The top solid lines should be drawn, and the dashed lines on the bottom would be drawn, also. The slashes are just filling.

3 lines of symmetry.
Meridians are lines of longitude that are drawn from the North to South poles.
