Answer: 7) No 8) No
Explanation:
According to the Pythagoras theorem of the right triangle,
Square of largest side = Sum of square of other two sides.
8) Given sides: 5cm, 12cm, 14cm
Here, Largest sides = 14 cm
![5^2+12^2=25+144=169\\eq14^2 \ \ \ [14^2=196]](https://img.qammunity.org/2022/formulas/mathematics/high-school/p2hlp876h3ru86x5i5kjrcr9y7zhcq8auw.png)
These sides do not represent a right triangle.
7) Given sides: 9m, 4m, 5m
Largest side = 9 m
![4^2+5^2=16+25=49\\eq 9^2 \ \ \ \ \ [9^2=81]](https://img.qammunity.org/2022/formulas/mathematics/high-school/oixvc346dyob54blkr4z4bq7tzufh8jz1w.png)
These sides do not represent a right triangle.
