## FAQs on NCERT Solutions for Class 7 Maths Chapter 14 - Symmetry

Q1. What is Rotational Symmetry and What is the Order of Rotational Symmetry?

**Ans:** A figure is said to have the rotational symmetry if it fits into itself more than once during a complete rotation.

The number of times a figure fits onto itself in one complete rotation is called the order of rotational symmetry.

Q2. After Rotating by 60^{0} about a Center, a Figure Looks Exactly the Same as its Original Position. At What Other Angles will this Happen for the Figure?

**Ans:** The figure will look exactly the same as its original position at 120^{0}, 180^{0}, 240^{0}, 300^{0}, and 360^{0}.

Q8. How can students solve symmetry questions of Chapter 14 of Class 7 Maths easily?

**Ans:** Certain requirements must be met for a figure to be considered symmetrical. To assess and identify the given figure as symmetrical while utilizing the understanding of these criteria, students must have committed observational skills and attentiveness. As a result, these requirements or logic must be remembered. The following are a few of them.

Regular Polygon Lines of Symmetry: The number of lines of symmetry in a regular polygon equals the number of sides.

Rotational Symmetry Order: The number of times an object appears the same after a complete 360-degree turn is known as the order of rotational symmetry. It will be 4, for example, for a square.
