Wendy described four triangles as shown below:
Triangle A: All sides have length 9 cm.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°.
Triangle C: Two angles measure 50°.
Triangle D: Base has length 8 cm, and base angles measure 45°.
Which triangle is not a unique triangle?
Triangle A
Triangle B
Triangle C
Triangle D

- anonymous

do you know it?

- anonymous

do you know what a unique triangle is?

- anonymous

Yes

- anonymous

what is it?

- anonymous

Unique triangles are triangles that do not have an equivalent

- anonymous

do you know what an equivalent is?

- anonymous

An equivalent is something that is equal in amount or value

- anonymous

so if you know what a unique triangle is, then eliminate the options that are unique triangles and that should give you the answer

- anonymous

I got A

- anonymous

triangle c is not unique

- anonymous

do you know why?

- anonymous

It's c?

- anonymous

yes, because the angles have to be 50 degrees, but that doesn't mean the sides of the triangle have to be a certain length

- anonymous

do you get it now?

- anonymous

Yea

- anonymous

Thanks! I have more questions :)
Do I post them here?

- anonymous

Which of the following possibilities will form a triangle?
Side = 10 cm, side = 5 cm, side = 6 cm
Side = 10 cm, side = 6 cm, side = 3 cm
Side = 11 cm, side = 5 cm, side = 6 cm
Side = 11 cm, side = 5 cm, side = 5 cm

- anonymous

do you know what the triangle inequality theorem is?

- anonymous

if you do, it should help

- anonymous

two sides added together should be larger than the third side of the triangle

- anonymous

5+6 is greater than 10 so the first one would work, sorry I had a typo in the last reply

- anonymous

Ok that's would I was gonna say! :)

Tim wrote the following statement:
"You can only draw one unique isosceles triangle that contains an angle of 70°."
Which statement is true?
Tim is incorrect, because more than one triangle can be drawn with the given information.
Tim is correct, because only one unique triangle can be drawn with the given information.
Tim is incorrect, because the triangle described cannot be drawn with the given information.
None of the above.

do you know what supplementary angles are?

- anonymous

it means you can add them together to get 180

- anonymous

Ok

- anonymous

so solve this equation : 8x+60+80=180

- anonymous

to get 5

- anonymous

5*8+60+80=180, so 5 is correct

- anonymous

Oh okay!
