Example Question #571 : Plane Geometry
Does the black line in the figure represent a line of symmetry?
Possible Answers:
No
Yes
Correct answer:
No
Explanation:
When you are trying to decide if a line represents a line of symmetry you can think about folding the figure across that line. Once you make the fold, do all of the parts line up on top?
If yes, then the line represents a line of symmetry.
If no, then the line does not represent a line of symmetry.
This line does not represents a line of symmetry because if you fold on the black line, one side will not lay on top of the other with parts that match up.
