Alicia drew a pentagon with equal side length and equal angles.Then she added red lines of symmetry to her drawing. How many lines did she draw?

Respuesta :

The sum of angles in a regular pentagon is
180*(5 - 2) = 540°
Each internal angle is 540/5 = 108°.

Each vertex creates a line of symmetry to the midpoint of the opposite side,
as shown in the figure.

Answer: 5 lines of symmetry.
