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
=
=
= 36°
