Worked practice questions

Which of these is another name for reflection symmetry?

  1. Mirror symmetry
  2. Scale symmetry
  3. Helical symmetry
  4. Rotational symmetry
Show answer and solution

Correct answer: A. Mirror symmetry

1. Reflection symmetry means a figure is unchanged when reflected, so it matches its own mirror image. 2. That is why it is also called line symmetry or mirror symmetry. 3. Scale, helical and rotational symmetry describe resizing, screw motion and turning, not mirroring. _Source: Wikipedia, Reflection symmetry (lead section)_

A solid object with reflection symmetry has what in place of a line of symmetry?

  1. A point of symmetry
  2. A plane of symmetry
  3. A curve of symmetry
  4. A ring of symmetry
Show answer and solution

Correct answer: B. A plane of symmetry

1. In two dimensions a figure is mirrored across a line or axis. 2. In three dimensions the mirror becomes a flat surface, called a plane of symmetry. 3. Points, curves and rings are not mirrors, so they do not define reflection symmetry. _Source: Wikipedia, Reflection symmetry (lead section)_

A square can be folded in four different ways so that its edges match. How many axes of symmetry does it have?

  1. Two
  2. Three
  3. Four
  4. Eight
Show answer and solution

Correct answer: C. Four

1. Each fold that makes the edges match is one axis of symmetry. 2. A square folds along two midlines and two diagonals, giving four folds. 3. Two is the count for a non-square rectangle, and eight counts all symmetry motions including turns. _Source: Wikipedia, Reflection symmetry, section Symmetric function_
