Question

please answer by solving​

Answer 1

Answer:

b) is not possible .

Explanation:-

First we have to know what is the property of a triangle . That is ,

The sum of the small two side must be bigger that the other side . If a triangle has this property it is a triangle and in a Isoceles triangle 2 side must be equal . The other side must be unequal .

Let's see :-

a) The sum of 3+3 = 6 . As , 6 is bigger than 4 it's a Isoceles triangle .

b) The sum of 4+4 = 8 which is equal to the third angle . So, it's not a Isoceles triangle .

c) The sum of 7 + 1 = 8 which is greater that 7 . So, it's a Isoceles triangle .

d) The sum of 1 + 12 = 13 which is greater than 12 . So it's also a Isoceles triangle .

Only option b) does not meets the requirements . So, only b) is not a Isoceles triangle .

Hope it helps friend!
