Question

1. The angle measures and/or side lengths of a triangle are described. Determine whether the conditions given determine a unique triangle, determine more than 1 triangle, or cannot make a triangle. Explain how you know this.
(a) 3 in., 3 in., 3 in.
(b) 1 in., 2 in., 3 in.
(c) 35o, 60o, 4 in., arranged in listed order
(d) 4 in., 5 in., 50o, arranged in listed order

Answer 1

o=degrees
please help i really dont understand it

Answer 2

i have already done the first one

Answer 3

to make a triangle the sum of any 2 sides must be greater than the tghird side.

For example you cannot make a triangle if the 3 values given are 1 , 1 and 3
because 1 + 1 is less than 3

check out (b) what do you think?

Answer 4

* third side

Answer 5

that it can make a triangle?
can there be more than one triangle or is it just one triangle

Answer 6

yeah i know

Answer 7

Hmm...
What section are you on in your math course? I don't want to explain using concepts you're unfamiliar with

Answer 8

7th grade math with angles and triangles

Answer 9

I was gonna say what subject/section... not what grade lol
Trigonometry? Geometry? Pre-Algebra (probably not that)?

Answer 10

oh i have no idea let me check

Answer 11

*also I really do NOT remember what a unique triangle is, so here's a link while I try to figure that out lol

Answer 12

All it says is "Extended Problems: Reasoning"

Answer 13

Well, I'm not sure about that, but from the problem my best guess is you're working on an "ambiguous case" problem (Those are terrible. I hate them. xD).

Answer 14

just that i have trouble with the angles and if you have different lengths, can it make more than one or just one

Answer 15

x_x
I SHOULD know how to do this but my brain dies when I attempt to figure this out e_e
@Directrix lol

Answer 16

lol

Answer 17

Did you have a look at the link I gave you?

Answer 18

ill just try it on ,y own cause im getting in trouble because im still on this and not on my homework

Answer 19

Well... you can do your homework while sneakily looking at the page link I sent you (;
It does talk about math formulas after all >_>

Answer 20

i saw it but my family is so freaking cranky

Answer 21

Triangle Inequality Theorem:

One side of a triangle is less than the sum of the other two sides.

Answer 22

lol sounds like my mom :p

Answer 23

@Directrix can help you (:

Answer 24

lol and thanks i just need help with the angles now

Answer 25

That lets this option in: (a) 3 in., 3 in., 3 in.

3< 3 + 3 is true.

Answer 26

i got that and the second one is that it cant make a triangle right

Answer 27

This is not true: (b) 1 in., 2 in., 3 in.

because 3 < 1 + 2 gives 3< 3 which is false.

Answer 28

ok thanks what about the angles

Answer 29

Two angles and the non-included side determine a unique triangle. AAS Theorem
