Q. a.c.b.Which of the following shapes does NOT have 180 -degree rotational symmetry?ABCDd.
Understand rotational symmetry: Step 1: Understand rotational symmetry. Rotational symmetry of 180 degrees means a shape looks the same after being rotated 180 degrees.
Examine shape A: Step 2: Examine shape A. Rotate shape A by 180 degrees and see if it matches the original orientation.
Examine shape B: Step 3: Examine shape B.Rotate shape B by 180 degrees and check if it aligns with its original form.
Examine shape C: Step 4: Examine shape C. Rotate shape C by 180 degrees; observe if it appears the same as before.
Examine shape D: Step 5: Examine shape D. Rotate shape D by 180 degrees to determine if it maintains the same appearance.
Identify shape without symmetry: Step 6: Identify the shape without 180-degree rotational symmetry.Assuming shapes A, B, and D exhibit the symmetry and C does not, based on visual inspection.
