The correct option is
C Yes
Let a,b.c are the sides of the triangle
Given, sides of triangle are
a=5 cm
b=12 cm
c=13 cm
hypotenuese rule of right angled triangle =a2+b2=c2
⇒c2=132=169
⇒a2+b2=52+122=25+144=169
⇒a2+b2=c2
Hence, by the converse of Pythagoras theorem, the triangle is a right-angled triangle with Hypotenuse being the largest side = 13 cm.
