Question

the ratio of the lengthsof the three line segment is 1:2:3 if sum of their length is 12 cm can these line segments form atriangle​

Answer 1

Step-by-step explanation:

If the ratio is 1:2:3, then for eg the lengths of sides are 2,4,6 cm respectively. But According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. So, no these line segments cannot form a triangle
