1. Find whether it is possible to draw a triangle with line segments of lengths​

Answer 1

yes in all cases it is possible.

a. will be unequal sides of triangle.

c. will be an equilateral triangle.

Answer 2

Step-by-step explanation:

a) Not possible because sum of two sides must be greater than third side. But in this case ,

3+4 = 7

it is equal to 7 ,means to third side .

so , triangle will not be possible.

b) This is possible , because

12+12>24

12+12>24

12+12>24

so here it is possible to draw triangle .

In this case it will be equilateral triangle.
