Answer:
C. 18°
Step-by-step explanation:
The <em>order of symmetry</em> (n) is the number of times a shape fits onto itself during a complete turn through 360°.
The <em>angle of rotational symmetry</em> (θ) is the smallest angle through which the shape must be rotated to coincide with itself.
To find the angle, y<em>ou divide the number of degrees in a circle by the order of symmetry</em>.
θ = 360/n
= 360/20
= 18°
Your answer is C. 6.5!
