What is symmetry?
Symmetry is when a shape or pattern remains unchanged even after flipping, rotating, or reflecting. It follows a consistent rule, creating a balanced and identical appearance on both sides. Click here for more: https://www.tiwariacademy.com/ncert-solutions/class-6/maths/

What is the method used to divide a rectangle into identical squares?
To divide a rectangle into identical squares, parallel lines are drawn at equal distances along its length and width. This ensures that all resulting squares have equal side lengths and maintain uniformity. Click here for more: https://www.tiwariacademy.com/ncert-solutions/class-6/maths/

Acar runs at a uniform rate on a circular track of radius 100m taking 62.8 s on each lap. What is the average velocity and average speed of car for one complete lap?
(b) Radius of circular track R = 100 m and time taken by car to complete one lap of circular track t = 62.8 s. Total displacement of car on covering a lap = 0 ∴ Average velocity of car = total displacement/total time = 0/62.8 s = 0 Total distance covered by the car in one lap s = 2πR = 2 × 3.14 × 10Read more
(b) Radius of circular track R = 100 m and time taken by car to complete one lap of circular track t = 62.8 s.
Total displacement of car on covering a lap = 0
∴ Average velocity of car = total displacement/total time = 0/62.8 s = 0
Total distance covered by the car in one lap s = 2πR = 2 × 3.14 × 100 = 628 m
∴ Average speed of car = total distance/total time = s/t = 628 m/62.8 s = 10m s⁻¹ .
