Question

10. Define : (i) Parallel Lines
(ii) Radius of a circle​

Answer 1

Answer:

$\huge\bold{parallel \:line}$

• In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
• Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.

$\huge\bold{radius\:of\:a\: circle}$

• The distance from the center to the circumference of a circle. It is half of the circle's diameter.

Answer 2

Answer:

(i) Lines on a plane that never meet. They are always the same distance apart.

(ii) In clasical geometry, a radius off a circle or sphere is any of the line segments from its center to its perimeter and in more modern usage.It is also their length.
