Question

1. describe both rotational symmetry and reflection symmetry. find four examples of symmetry in your classroom.

Explanation:

Rotational symmetry is when a shape can be rotated around a point and still look the same. Reflection symmetry is when a shape can be divided into two identical halves by a line of reflection. In a classroom, a circular clock has rotational symmetry. A rectangular white - board has reflection symmetry (vertically and horizontally). A square tile on the floor has both rotational (rotations of 90°, 180°, 270°) and reflection symmetry. A book with a rectangular cover has reflection symmetry.

Answer:

Rotational symmetry: A shape looks the same after rotation. Reflection symmetry: A shape is divided into two identical halves by a line. Examples: Circular clock (rotational), rectangular white - board (reflection), square floor tile (both), rectangular - covered book (reflection).
