Final answer:
The letter with two types of symmetry is H, which has reflection and rotational symmetry.
Step-by-step explanation:
The letter of the alphabet that has two types of symmetry is the letter H. The letter H has both reflection symmetry and rotational symmetry.
To illustrate its symmetries:
- Reflection symmetry: If we fold the letter H in half vertically, the left side will be a reflection of the right side. This means that the left half can be superimposed onto the right half.
- Rotational symmetry: If we rotate the letter H 180 degrees, it will look the same as it did before the rotation. This means that it has rotational symmetry of order 2.
