Answer 1

Answer:

1) There may be errors due to the thickness of the ruler and angular viewing by using a ruler. These errors are eradicated by using a divider. So, it is better to use a divider with ruler, than a ruler only, while measuring the length of a line segment.

2) (i) AB = CD

(ii) BC < AB

(iii) AC > BD

(iv) CD < BD

Hope this is helpful for you.
