Question

find whether the measures 5cm , 8cm , 17cm form a triangle or not ?
​

Answer 1

Answer:

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

So according to this:-

5cm+8cm=11m [17>11]; as the sum of two sides are less than the other side then this cannot be a triangle..
