Question

the length of two sides of a triangle are 12cm and 15 cm . between what two should the length of third side fall.​

Answer 1

Answer:

the third sides leanth should 1 cm -26 cm.

because (we know in case of a triangle the addition of the first and the second side is always getter than the third side )

I mean ,12+15=27

Answer 2

Explanation

Property used: In a triangle, the sum of two sides is greater than the third side.

The third side should be less than the sum of two given sides

12 + 15 = 27 cm

So the third side should be less than 27 cm.

Also, the third side should be more than the difference of two sides.

15 - 12 = 3 cm

So the third side should be more than 3 cm.  

So we conclude that the length of the third side should fall between 3 cm and 27 cm.

Final answer

27 cm > Third side > 3 cm. (meaning that third side should be smaller than 27 cm but greater than 3 cm)
