Lisa wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 65°." Which statement is true? Lisa is incorrect, because more than one triangle can be drawn with the given information. Lisa is correct, because only one unique triangle can be drawn with the given information. Lisa is incorrect, because the triangle described cannot be drawn with the given information. None of the above.

Tina described four triangles as shown below: Triangle A: All sides have length 12 cm. Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Base has length 15 cm, and base angles measure 40°. Triangle D: All angles measure 60°. Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D

OpenStudy (anonymous):

C?

OpenStudy (holly00d1248):

Ya

OpenStudy (holly00d1248):

wait not C

OpenStudy (anonymous):

haha i was a bout to ask you. so then what is it?

OpenStudy (holly00d1248):

OpenStudy (anonymous):

so??

OpenStudy (holly00d1248):

I d go with D

OpenStudy (anonymous):

kk thx:)

Which of the following possibilities will form a triangle? Side = 15 cm, side = 7 cm, side = 7 cm Side = 15 cm, side = 7 cm, side = 9 cm Side = 14 cm, side = 6 cm, side = 7 cm Side = 14 cm, side = 6 cm, side = 8 cm

OpenStudy (anonymous):

What do you think @Holly00d1248

OpenStudy (anonymous):

??

OpenStudy (tkhunny):

Lisa is not correct. 65-57.5-57.5 50-65-65 That's two entirly different isosceles triangles with a 65º angle.

OpenStudy (anonymous):

thx:)

OpenStudy (holly00d1248):

Not sure on this one ask @tkhunny

OpenStudy (anonymous):

ok what do you think @tkhunny

OpenStudy (tkhunny):

You must use the Triangle Inequality. Add up all three pairs (2 at a time) and make sure the sums are greater than the remaining side. I demonstrate one... Side = 14 cm, side = 6 cm, side = 7 cm 14 + 6 > 7 -- Good 14 + 7 > 6 -- Good 6 + 7 < 14 -- No Good. Not a triangle.

OpenStudy (anonymous):

ok so which one would be all three good??

This is your assignment. Go!

"=" doesn't work. It requires ">".
