Question

A triangle can be formed with side lengths 3 in, 5 in, and 9 in.

True
False

Answer 1

That's the triangle inequality.

Answer 2

Test for each:

a = 3 in , b = 5 in , c = 9 in

a + b > c
a + c > b
c +b > a

if it's true for all , then you can form a triangle with this lengths if not, the triangle sides will never intersect.

Answer 3

So its False

Answer 4

@TrojanPoem

Answer 5

a + b = 8
and c = 9
so?

Answer 6

so its true

Answer 7

no
a + b < 9
and we require a + b > 9

Answer 8

understand?

Answer 9

Yes! Thank you!!
