Question

Which dimensions cannot create a triangle

Answer 1

Answer: the last one

EXPLAINATION:

The first one follows the rule a+b=c, and when you add all the angles it equals 180

The second one when you add up all of the angles, it is 180

The third one follows a2+b2=c2. 5(5)+12(12)= 169, 13(13)=169

The last one does not follow any of the triangle rules.
