Answer:
Let first side= 5 cm
second side= 12 cm
third side = 13 cm
To prove this triangle to be right angle triangle, we need to prove Pythagoras Theorem
[tex]5^{2}[/tex]=25
[tex]12^{2}[/tex]=144
[tex]13^{2}[/tex]=169
169= 25+144
169=169
According to Pythagoras theorem ,
[tex]p^{2}[/tex]+[tex]b^{2}[/tex]=[tex]h^{2}[/tex]
since, it follows Pythagoras theorem,
Hence, it is a Right angle Triangle
