Q:
# What kinds of symmetry do these letters and numbers have? Choosing best answer? What kind(s) of symmetry do these have? F 3 E Point, line, plane, or none?

Accepted Solution

A:

Answers:

Letter F: none

Number 3: line and plane simmetry

Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180Β° returns the same original figure.

None of the objects given result the same when you rotate them 180Β°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

Letter F: none

Number 3: line and plane simmetry

Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180Β° returns the same original figure.

None of the objects given result the same when you rotate them 180Β°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.
