Question

which diagram has all of the correct lines of reflectional symmetry for the regular pentagon?

Explanation:

Step1: Recall the property of a regular pentagon

A regular pentagon has \(n = 5\) sides. The number of lines of reflectional symmetry of a regular polygon is equal to the number of its sides.

Step2: Analyze each diagram

• A regular pentagon has 5 lines of reflectional symmetry. Each line of symmetry passes through a vertex and the mid - point of the opposite side.

Answer:

The second diagram (the one with 5 lines of symmetry) is the correct one.
