b. 5cm, 13cm, 12cm​

Answer 1

Answer:

it's a right angled triangle

Step-by-step explanation:

( here we have taken 13cm as the hypotenuse because in a triangle side opposite to tha largest angle is the largest side of that triangle)

from equation 1

169=169

hence it is following the Pythagoras theorem so it's a right angled triangle
