Answer:

Figure 1 (The Star)

Explanation:

Line symmetry is symmetry created by a line that divides a shape. Only the "star" (Figure 1) and the "A" (Figure 2) can be split through the center into two identical halves, therefore we can rule out Figures 3 & 4. Rotational symmetry is when a shape looks the same after a partial turn. Rotational symmetry is only true for the "star" (Figure 1) which will be symmetric every 72-degree (360/5) turn. However, the "A" (Figure 2) can only be flipped 180 degrees to remain symmetric.

Therefore Figure 1 is the only figure with both rotational and line symmetry.

Option D is correct (star)

It has 5 line of symmetry and has rotational symmetry as well
