## Example Questions

### Example Question #1 : Line Of Symmetry: Ccss.Math.Content.4.G.A.3

Do the black lines in the figure represent lines of symmetry?

Yes

No

Yes

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.

These lines represent lines of symmetry because if you fold on the black lines, then one side would lay on top of the other and the parts would match up.

### Example Question #15 : Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles

Does the black line in the figure represent a line of symmetry?

No

Yes

Yes

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 represents a line of symmetry because if you fold on the black line, then one side would lay on top of the other and the parts would match up.

### Example Question #2 : Line Of Symmetry: Ccss.Math.Content.4.G.A.3

### Example Question #3 : Line Of Symmetry: Ccss.Math.Content.4.G.A.3

Do the black lines in the figure represent lines of symmetry?

No

Yes

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.

These lines do not represent lines of symmetry because if you fold on the black lines,  one side will not lay on top of the other with parts that match up.

### Example Question #542 : Plane Geometry

Does the black line in the figure represent a line of symmetry?

Yes

No

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.
