Question

Is it possible to make a triangle with 3.1cm, 1.9cm, 5.1cm as its length? Give reasons.​

Answer 1

Answer:

no

Step-by-step explanation:

3.1 , 1.9 , 5.1

if we add 2 sides the 3rd side will always greater so the triangle will possible.

$3.1 + 1.9 = 5.0 < 5.1$

$1.9 + 5.1 = 7.5 > 3.1$

$3.1 + 5.1 = 8.2 > 1.9$

if one is less that the third side the triangle will not possible look 1st addition 5.0 < 5.1
