Question

is it possible to construct a triangle with the line segment of length 5 cm is 7 cm 12 CM ?why?​

Answer 1

Answer:

no

Step-by-step explanation:

there is a rule of the sides of triangles

it is always true for a triangle to be constructed that sum of any 2 sides is greater than (not equal to) the 3rd side.

This rule is not followed here as 5+7=12 when it should be that a+b>12 where a+b are 2 sides

hence , no

Answer 2

Step-by-step explanation:

no, because when we sum 5+7=12 it is rule when we sum two angle of triangle is greater than third angle.
