Question

Which set of measurements would NOT form a triangle?

a) 7, 12, 12

b) 7, 12, 5

c) 7, 12, 17

d) 7, 12, 7

Answer 1

For the measurements to be good, two sides added together have to be greater than the other side. The only one that doesn't work here would be B, because 7+5=12 abd 12 isn't greater than 12. So B would not form a triangle.

Answer 2

B wouldn't because the two sides must be greater when added up then the biggest angle

Answer 3

ohhhh

Answer 4

so its c ?

Answer 5

No, the greatest angle measure has to be less than the other two added up. so C cant be it because 7+12>17 so it could form a triangle

Answer 6

but 7+12= 19 > 17

Answer 7

Exactly, when the sum is greater, which in this case 19>17 it means that it can form a triangle. This question is asking which one cannot form a triangle.

Answer 8

omg, i didnt see the not lol

Answer 9

Its fine good work, Im glad that you know have an understanding of the material. Have a good day!

Answer 10

none -.-

Answer 11

B wouldnt because 7+5=12, the sum needs to be greater not equal.
