Question

Which of the following can be the sides of a triangle [2cm,3cm,5cm ;3cm,6cm,7cm

;6cm,3cm,2cm]​

Answer 1

Answer:

None of these

Step-by-step explanation:

All sides of a triangle should Pythagorean triplets

Here,

a² + b² = c² = Pythagorean Triplet formula

1) 2² + 3² = 5²

  4 + 9 ≠ 25

2) 3² + 6² = 7²

   9 + 36 ≠ 49

3) 2² + 3² = 6²

   4 + 9 ≠ 36

Therefore, None of these can form a right angled triangle

Answer 2

Answer:

3cm,6cm,7cm

Step-by-step explanation:

This is because for a triangle to be possible sum of it's 2 sides must be greater than the 3rd side and 33+6=9>7 , 6+7=13>3 and 7+3=10>6 whereas for the other triangles this rule doesn't follow
