Can a triangle have sides with lengths 4 cm, 5 cm, and 12 cm?
Why or why not? Explain completely.
Yes
No

yes

Step-by-step explanation:

becusue they can be long as they want

No, there can not be a triangle with such dementions

Step-by-step explanation:

A triangle can not have sides with lengths 4cm, 5 cm, and 12 cm, because of the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. In our case taht is not true, because

4 cm + 5 cm = 9cm (the sum of the two sides)

9cm < 12cm (is smaller the the third side)

Which means that a triangle can not have such dementions.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
