Answer:
no parallel lines can be drawn
Step-by-step explanation:
Given a line and a point not on it, no lines parallel to the given line can be drawn through the point. you get an elliptic geometry.
The amount of lines of symmetry of a shape is equal to the number of sides that shape has.
A heptagon has 7 sides, so, there are 7 lines of symmetry.
Best of Luck!
