Question

Triangle Theorem

Answer 1

Okay the theorem you should know is that the other side is greater than the difference of the two sides and smaller than the sum of the two sides.

Answer 2

So, the answer is 4.2 < 7.8

Answer 3

I understand 6.0-1.8=4.2; 6.0+1.8=7.8 :)

Answer 4

sum of any 2 sides has to be larger than the remaining side to be able to construct a triangle

Answer 5

So, that would mean this triangle would exist.

Answer 6

The sides are 7.0 and 8.0

Answer 7

I would think so

Answer 8

What do you think, Dan?

Answer 9

yes, all you have to remember is that 2 sides total greater than the remaining side

works fine in that triangle

Answer 10

Got it

Answer 11

Like the range of the missing side, using that simple idea gives

x + 6 > 1.8
x + 1.8 > 6
x < 6 + 1.8


x > 4.2
x < 7.8
