Question

1. which capital letters have one or more lines of symmetry? select all that apply. a x b z c h d c 5. which shape is an example of rotational symmetry?

Explanation:

• For question 4:
• A line of symmetry is a line that divides a figure into two congruent parts.
• For letter \(X\), there are two lines of symmetry (horizontal and vertical).
• For letter \(H\), there are two lines of symmetry (horizontal and vertical).
• For letter \(C\), there is one line of symmetry (horizontal).
• For letter \(Z\), there is no line of symmetry.
• For question 5:
• Rotational symmetry is when a shape looks the same after a rotation of less than \(360^{\circ}\).
• Option \(A\) has rotational symmetry as it can be rotated by \(60^{\circ}\) (since \(360\div6 = 60\)) and still look the same.

Answer:

1. A. \(X\), C. \(H\), D. \(C\)
2. A.
