Please give me examlpes of objects having rotational symmetry and find its order of rotation and angle of rotation. Pls answer fast!!! I need the answer in an hour!!!

In an object after the rotational symmetry that object is appear to be the same after a fix rotation or certain number of rotation. Objects are might contain more than one rotating symmetry. The point of rotational symmetry is has to be turned to appear the similar on a different vertex or side. It cannot be the similar vertex or side.

Order 1 rotational symmetry objects :

• The isosceles triangle objects have Order 1 rotational of symmetry.
• The scalene triangle objects have Order 1 rotational of symmetry.
• The isosceles trapezoid objects have Order 1 rotational of symmetry.
• The trapezium objects have Order 1 rotational of symmetry.
• The kite objects have Order 1 rotational of symmetry.

Order 2 rotational of symmetry objects :

• The rectangle objects have Order 2 rotational of symmetry.
• The parallelogram objects have Order 2 rotational of symmetry.
• The rhombus objects have Order 2 rotational of symmetry.
• The ellipse objects have Order 2 rotational of symmetry.

Order 3 rotational of symmetry objects:

The equilateral triangles objects have Order 3 rotational of symmetry.

Order 4 rotational of symmetry objects:

The square objects have Order 4 rotational of symmetry.

Order 5 rotational of symmetry objects:

The regular pentagon objects have Order 5 rotational of symmetry.

Examples of Rotational Symmetry

which of the letters has rotational symmetry?

Solution:

Step 1:

A letter has a rotational symmetry, if its letter, behind a revolving of less than 360°, appears accurately the similar as that of the original image.

Step 2:

When S is rotated by means of 180°, it accurately fits on the original shape.So, the letter in shape 4 has a rotational symmetry.

Some other figures which satisfies rotational symmetry are circle, square, isosceles triangle...etc
