Awesome thanks for coming!
where is the question?
I'm gonna post it now :)
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
do you know it?
do you know what a unique triangle is?
what is it?
Unique triangles are triangles that do not have an equivalent
do you know what an equivalent is?
An equivalent is something that is equal in amount or value
so if you know what a unique triangle is, then eliminate the options that are unique triangles and that should give you the answer
I got A
triangle c is not unique
do you know why?
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
do you get it now?
Thanks! I have more questions :) Do I post them here?
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
do you know what the triangle inequality theorem is?
if you do, it should help
two sides added together should be larger than the third side of the triangle
5+6 is greater than 10 so the first one would work, sorry I had a typo in the last reply
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.
I am back
which one do you think it is
i know what it is
Ok I got a for this one
do you know what supplementary angles are?
it means you can add them together to get 180
so solve this equation : 8x+60+80=180
to get 5
5*8+60+80=180, so 5 is correct
Of course you get a medal :)
do you know what is the formula for the area of a circle?
I think the answer is A
I'm not sure
