what is the minimum angle of rotational symmetry for the quadrilateral shown below?\n60°\n90°\n180°\n360°
Answer
Explanation:
Step1: Recall rotational - symmetry concept
The minimum angle of rotational symmetry of a non - regular polygon is the smallest angle by which it can be rotated about a fixed point to coincide with itself. For a non - regular quadrilateral, if it is not a special case like a square or a rhombus etc., the minimum angle for it to coincide with itself is when it is rotated a full circle.
Step2: Identify the full - circle angle
A full circle has an angle of 360°.
Answer:
360°
