There are more than 4 values.

1) First draw up a triangle that looks possible.

All the angles are different so if you use a triangle that looks a bit like a 30,60, 90 degree triangle that will be good to work with.

2) Label the 3 angles correctly according to their relative angle size

3) Label the 3 sides

4) Now the smallest side is opposite the smallest angle etc so write 'smallest' and 'biggest' near the correct sides.

5) Now you know that smallest side < middle side Solve the inequality

6) You also know that the middle side < longest side. Solve the inequality.

7) So what do you know so far?

8) Now to be a triangle at all the sum of the 2 smallest sides must be longer than the long side.

Form the inequality and solve it.

9) So what have you found.

If you have questions then ask. You can take a photo of your pic on your phone and post it if need be.

I am very happy to help more if necessary but i want to be convinced that you are trying to help yourself first.

**Please no one else answer**
