Which of the following rotation operations are involutory? Match the rotation operations that achieve the same outcome.
Understand the Problem
The question asks to identify which rotation operations are involutory and to match rotation operations that achieve the same outcome. Involutory operations are those that, when applied twice, return the original configuration. The matching portion involves associating different operations to equivalent transformations.
Answer
Involutory: rotate 180°, flip up-down, flip left-right.
Involutory operations: rotate 180°, flip up-down, flip left-right.
Answer for screen readers
Involutory operations: rotate 180°, flip up-down, flip left-right.
More Information
Involutory operations return to the original state when applied twice, like a 180° rotation or horizontal flip.
Tips
Common mistakes include confusing a single operation with a sequence of operations or assuming non-involutory operations can apply.
