Answer 2

Answer:

1). Fold reflection symmetries = 5

2). Order of rotational symmetries = 10

3). Smallest angle of rotational symmetry = 36°

Step-by-step explanation:

A decagon has number of fold reflection symmetries = 5

[Fold reflection symmetries are the lines by which we can fold the shape into half]

Order of rotational symmetry of a decagon = 10

[Order of rotational symmetry means number of rotations by which the polygon maps itself in a complete rotation of 360°]

Smallest angle of rotational symmetry for a decagon

= $\frac{360}{\text{Number of sides in a regular polygon}}$

= $\frac{360}{10}$

= 36°
