Question

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

True
False

Answer 1

False, No Triangle can be formed with those side lengths. Here's why:
The sum of side a and side a has to be greater than side c.
a+b>c
3+5= 8
8 is not greater than 9

Answer 2

Answer:

False

Step-by-step explanation:

To find out if you can form a triangle from the measurements, you can compare the numbers.

If you add any combination of these number together, they need to be greater than the one you're comparing to.

3 + 5 needs to be greater than 9.

But it's not.

The other combinations work:

3 + 9 > 5

9 + 5 > 3

But since the first combination didn't work, these measurements will not form a triangle.
