A) \[3\text{ }cm,\text{ }4\text{ }cm,\text{ }6\text{ }cm\]
B) \[9\text{ }cm,\text{ }16\text{ }cm,\text{ }26\text{ }cm\]
C) \[1.5\text{ }cm,\text{ }3.6\text{ }cm,\text{ }3.9\text{ }cm\]
D) \[7\text{ }cm,\text{ }24\text{ }cm,\text{ }26\text{ }cm\]
Correct Answer: C
Solution :
If the sides of a triangle obey Pythagoras rule then triangle is right angled triangle. Here, \[{{(1.5)}^{2}}+{{(3.6)}^{2}}=2.25+12.96=15.21\,cm\] and \[{{(3.9)}^{2}}=15.21\,cm\] \[\therefore \] \[{{(1.5)}^{2}}+{{(3.6)}^{2}}={{(3.9)}^{2}}\]
