Question

triangle can be constructed with sides(in cm)

a ) 6 ,12,3
b ) 4,8,4
c ) 3,4,5
d ) 5,5,10
​

Answer 1

For the construction of a triangle we need the sum of any two sides must be greater than the third side. So

a) 6+12>3

12+3>6

6+3<12

so triangle is not possible

b) 4+4=8

8+4> 4

4+8>4.

So triangle is not possible

C) 3+4 >5

4+5 >3

5+3>4

yes triangle is possible

d) 5+5=10

5+10>5

10+5>5

So triangle is not possible
