Question

19cm,18cm,12cm can this form a triangle

Answer 1

$\huge \mathbb \pink{SOLLUTION:}$

$\huge\mathfrak\blue{No}$

$19+18+12=49$

$so \: triangle \: cannot \: be \: formed$

Answer 2

$\fbox\pink{Añswer}$

So, To find we have to know that the sum of the 2 side will be always greater than the other side.

So,

We can find in that way.

First,

19 + 18 = 37 {Greater than the other side}

18 + 12 = 30 {Greater than the other side}

19 + 12 = 31 {Greater than the other side}

Therefore we can say that 19cm,18cm and 12cm can form a triangle.
