Which of the following sets of measures cannot be the lengths of the sides of a right
triangle?
A
5 cm, 12 cm, and 13 cm
B
9 cm, 12 cm, and 17 cm
C
1 cm, 2.4 cm, and 2.6 cm
D
2.5 cm, 6 cm, and 6.5 cm

you can use the formula of pythagoras theorem to know what of them is wrong

in the first case

-5^2 + 12^2 =169

 13^2=169         ( it's a right equation so it can be lengths of right angle tri )

in the second case

_9^2 + 12^2 =225

  17^2 not equal 225

so these are the lengths that can't be a right angle triangle

14

step-by-step explanation:

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
