Question

What should be the length of the third side of an isosceles triangle if the lenght of the other two sides are 5 cm and 11 cm . Justify ?

Answer 1

Heya

Here goes your answer

In an isosceles triangle two sides must be equal

Here two of its sides are 5 cm and 11cm each

For the triangle to be an isosceles triangle, the third side should either be 5cm or 11cm

It can't be 5 cm

This is because the sum of any two sides of triangle should be greater than the third side

If the third side is 5 cm then the sum of two sides will be 5+5 = 10 which is less than 11cm(third side)

Therefore, the third side should be of the length 11cm

Hope it helps ^_^
