Answer 1

Answer:

this can be a right triangle if -

8²+12²=13² (pythagoras theorem)

64+144=169

208≠169

By comparing both LHS and RHS

They are not equal

therefore it's not a right angled triangle

pythagoras theorem-

sum of squares of 2 small sides of a triangle is equal to the square of the hypotenuse
