Answer:

169=169

Step-by-step explanation:

The pythagoras theorem states that if

[tex] {a}^{2} + {b}^{2} = {c }^{2} [/tex]

Then the triangle is a right triangle

So

[tex]{5}^{2} + {12}^{2} = {13}^{2} [/tex]

[tex]25 + 144 = 169[/tex]

[tex]169 = 169[/tex]

Therefore A is a right triangle

Answer:

Step-by-step explanation:

  • The pythagorian theorem :

now the longest edge is 13 cm so : 13²must be equal to 5²+12²

  • 5²+12²= 169
  • [tex]\sqrt{169}[/tex]= 13

so this triangle must be right angled
