In \(\triangle\text{XYZ},\) a, b, c denote the three sides, which of the following is incorrect?
1 a − b > c
2 a + c > b
3 a − b < c
4 a + b > c
Explanation:
a − b > c Actually, a − b < c ∀ a, b, c (the symbol, ∀ a, b, c means for all a, b, c) This implies that b − c < a; c − a < b

In order to duplicate agiven angle, which of the following instruments can be used?
1 Compass
2 Set Square
3 Protractor
4 Divider
Explanation:
Compass A Compass can be used to make the duplicate of any angle. A protractor can also be used to duplicate angles but only of integral values.So option A is correct.
