1.	Give a definition for each of the following terms. Are there other terms that need to be defined first ? What are they, and how might you define them ? (i) parallel lines (i) perpendicular lines (iii) line segment (iv) radius
Answer» (i) Parallel lines: Lines which don’t intersect any where are called parallel lines. (ii) Perpendicular lines: Two lines which are at a right angle to each other are called perpendicular lines. (iii) Line segment: it is a terminated line. (iv) Radius: The length of the line-segment joining the centre of a circle to any point on its circumference is called its radius.
