What type of symmetry is shown when a shape is reflected over an axis?

Reflective symmetry is characterized by a shape being identical on both sides of a dividing line, also known as an axis of symmetry. When a shape is reflected over an axis, one half of the shape is a mirror image of the other half. This property is commonly observed in various geometric figures, such as butterflies or the letter "A," where if you were to fold the shape along the axis, both halves would perfectly overlap.

In contrast, radial symmetry involves a shape that is symmetrical around a central point, as seen in starfish or flowers. Translational symmetry involves a shape being repeated at regular intervals in a specific direction, which is not the focus of reflection. Rotational symmetry pertains to a shape that looks the same after being rotated around a central point by a certain angle. Thus, reflective symmetry is the correct term for the scenario described.
