Question

give definition for each of the following teams. (a) parallel lines (b) perpendicular (c) radius of a circle (d) square​

Answer 1

Answer:

a) Parallel lines :

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.

b) Perpendicular lines :

Perpendicular lines are lines that intersect at a right (90 degrees) angle.

c) Radius of a circle :

In classical geometry, a radius of 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.

d) Square :

a plane figure with four equal straight sides and four right angles.
