Answer:

5 right triangle

6 not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = 13^2

25+144 = 169

160 = 169

This is true so this is a right triangle

15^2 +16^2 = 18^2

225 +256 = 324

481 does not equal 324

This is not a right triangle

Answer:

5. Yes

6. No

Step-by-step explanation:

5. 13² = 12² + 5²

169 = 144 + 25

169 = 169

Satisfies pythagoras theorem, so it is a right angle triangle

6. 18² = 16² + 15²

324 = 256 + 225

324 = 481 (false)

Doesn't satisfy the pythagoras theorem, so it is not a right angle triangle
