Answer: 7) No 8) No
Step-by-step 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
[tex]5^2+12^2=25+144=169\neq14^2 \ \ \ [14^2=196][/tex]
These sides do not represent a right triangle.
7) Given sides: 9m, 4m, 5m
Largest side = 9 m
[tex]4^2+5^2=16+25=49\neq 9^2 \ \ \ \ \ [9^2=81][/tex]
These sides do not represent a right triangle.
