The central angle O is a complete angle, so its measure is 360°. It is divided into 5 equal parts, so each of them has a measure of 360°/5=72°
Answer:
The least angle of rotation is [tex]72^o[/tex].
Step-by-step explanation:
Rotational symmetry is the amount of degrees you must turn an object so it looks exactly the same.
For,
Regular polygons use the following formula to find out how much you must turn an object to carry onto itself,
Angle of rotation[tex]=\frac{360^o}{n}[/tex],
Where [tex]n[/tex] is number of sides,
For pentagon [tex]n=5[/tex]
On substitution,
Angle of rotation[tex]=\frac{360^o}{n}=\frac{360^o}{5}=72^o[/tex]
The least angle of rotation is [tex]72^o[/tex].
