1.
When we measure the length of a line segment by ruler, there may be some errors due to its thickness and angular viewing. These errors can be removed by measuring a line segment with the help of a divider. Hence, the use of a divider is better than a ruler.
2.
The disadvantage in comparing line segments by mere observation is that, sometimes the difference in lengths between two line segments may not accurate. So, we cannot always be sure about our usual judgement.
e.g. In the given figure, the line segments \(\overline{ PQ } \) and \(\overline{ RS } \) seems to be equal but actually they are not equal.
3.
We know that,
An angle which is smaller than a right angle is called an acute angle.
An angle with measure 90° is called a right angle.
An angle which is greater than a right angle but smaller than a straight angle is called an obtuse angle.
An angle with measure 180° is called a straight angle.
An angle which is greater than a straight angle but smaller than a complete angle is called a reflex angle.
Now, from these results
(a) Given angle is smaller than a right angle, so it is an acute angle.
(b) Given angle is more than a right angle, so it is an obtuse angle.
(c) Given angle is a right angle.
(d) Given angle is more than a straight angle, so it is a reflex angle.
(e) Given angle is a straight angle.
(f) Both angles are smaller than a right angle, so both these are acute angles.
