Answer:
By pythagoras theorem,
a^2 + b^2 = c^2
5^2 + 12^2
= 25 + 144
=169
= 13^2
Thus it is an right angle triangle

Answer:
Yes , It is a right Triangle.
Step-by-step explanation:
Let the triangle be ∆ABC , with AC as the hypotenuse.
L.H.S. = AB² + BC²
= 5² + 12²
= 25 + 144
= 169 units
R.H.S. = AC²
= 13²
= 169 units
.°. L.H.S. = R.H.S.
.°. By Converse of Pythagoras theorem,
∆ ABC is a Right Triangle.
