Number of lines of symmetry and the order of rotational symmetry in a playing card with hearts and a 8
Understand the Problem
The question is asking for two specific properties of a playing card featuring hearts and the number 8: the number of lines of symmetry and the order of rotational symmetry. To solve this, we need to analyze the card's design to determine how many ways it can be folded or rotated to look the same.
Answer
1 line of symmetry, rotational symmetry order 2.
The playing card with hearts and an 8 has 1 line of symmetry (a vertical line through the center) and an order of rotational symmetry of 2 (180° rotation).
Answer for screen readers
The playing card with hearts and an 8 has 1 line of symmetry (a vertical line through the center) and an order of rotational symmetry of 2 (180° rotation).
More Information
Most standard playing cards like the 8 of Hearts have a design that allows them to be flipped 180° without altering their appearance, giving them an order of rotational symmetry of 2.
Tips
A common mistake is to assume more lines of symmetry because of the repetitive design on a card, but for many cards like an 8, there's just the vertical line.
