question 7 of 25

reflectional symmetry is the quality a design has if it maintains all characteristics when it is ______ lying in its plane.

a. rotated about a point
b. reflected about an axis
c. translated along a line

Explanation:

Analyze the definition of reflectional symmetry

Reflectional symmetry (or line symmetry) is a characteristic of a figure where it remains unchanged after a reflection transformation is applied.

Evaluate the given options

• A. rotated about a point: This describes rotational symmetry, not reflectional symmetry.
• B. reflected about an axis: This directly matches the definition of reflectional symmetry, where a design is reflected across a line (axis) lying in its plane and remains identical.
• C. translated along a line: This describes translational symmetry, not reflectional symmetry.

Select the correct option

Option B is the correct choice because reflectional symmetry specifically involves reflecting a design about an axis.

Answer:

• A. rotated about a point
• B. reflected about an axis (Correct answer)
• C. translated along a line
