A triangle can be formed with side lengths 4 in, 5 in, and 8 in.

True
False

Answer 1

@Michele_Laino

Answer 2

add the smaller numbers together, and if it is bigger than the bigger number, than it is a triangle

Answer 3

Use the Triangle Inequality Theorem

Answer 4

if you don't know what it is, here is a website that shows you what it is: http://hotmath.com/hotmath_help/topics/triangle-inequality-theorem.html

Answer 5

I think that it is true

Answer 6

so find the sum of 4+5

Answer 7

and if 4+5 is greater than 8, it is true, if not, it is false

Answer 8

yea 4+5=9 so its true!

Answer 9

You are correct!

Answer 10

can i ask you one more question please

Answer 11

sure

Answer 12

How many triangles can be made if one angle is 95° and another angle is acute?

1
2
More than 2
None

Answer 13

okay, so an acute angle is an angle less than 90 degrees

Answer 14

ok

Answer 15

and a triangle can be made with 3 angles added up to 180 degrees, right?

Answer 16

yea

Answer 17

so what do you think the answer is

Answer 18

more than 2

Answer 19

correct, i think

Answer 20

I am not 100% sure though, but I still think you are correct

Answer 21

ok lets hope for the best! :)

Answer 22

okay, bye

Answer 23

here is my reasoning:
we have another 85 degrees which have to be subsdivided in 2 angles, now being 85 < 90, then each of those of two angles also is less than 90 degrees

Answer 24

so what do you think it is?

Answer 25

I think it is more than 2 triangles, since we have these subsequent triangles:
95, 40, 45
95, 50, 35
95, 55, 30

Answer 26

ok thanks :)

Answer 27

I agree with @Michele_Laino
