What is the number of lines of symmetry and the order of rotational symmetry in a playing card with diamonds and the number 5?
Understand the Problem
The question is asking for two specific properties of a playing card decorated with diamonds and the number 5: the number of lines of symmetry and the order of rotational symmetry. To solve this, we need to analyze the shape of the card and its patterns to determine these properties.
Answer
0 lines of symmetry, order 2 rotational symmetry.
The 5 of Diamonds playing card has 0 lines of symmetry and an order of rotational symmetry of 2.
Answer for screen readers
The 5 of Diamonds playing card has 0 lines of symmetry and an order of rotational symmetry of 2.
More Information
A standard playing card such as the 5 of Diamonds can be rotated 180 degrees and still look the same, which gives it a rotational symmetry of order 2. However, due to its asymmetrical arrangement of symbols, it lacks reflective symmetry.
Tips
One common mistake is assuming the card has reflective symmetry due to its regular shape, but the number and arrangement of diamonds disrupt this.
