Question 838183
No, it is not possible, because {{{5+7=12}}} .
A straight line is the shortest distance between two points.
As a conmsequence one side of a triangle must be shorter than the sum of the other too.
If a triangle has side AB measuring 5 centimeters and side BC measuring 7 centimeters,
{{{drawing(700,100,-6,8,-1,1,triangle(-4.98,0,6.99,0,0,0.41),
locate(-2.5,0.5,5),locate(3.5,0.5,7),locate(0,0.7,B)
locate(-5.3,0.1,A),locate(7.1,0.1,C)

)}}}
side AC is the straight line distance from A to C, and it has to be shorter than the distance going from A to C passing through B.
The distance passing through B is {{{5cm+7cm=12cm}}} , but AC must be shorter than that.
