Law of cosine is :
c^2<span> = a^</span>2<span> + b^</span>2<span> − 2ab cos(theeta)
</span>so in case of right triangle , angle is 90 degree:
putting 90 degrees into formula:
c^2 = a^2 + b^2<span> − 2ab cos(90)
</span>As we know that:
cos90 = 0
c^2 = a^2 + b^2<span> − 2ab (0)
</span>c^2 = a^2 + b^2<span> - 0
</span>c^2 = a^2 + b^2 ( this is <span>pythagorean theorem ).
</span>So the above statement is True.
