Did you know...

That we can determine if a triangle is possible from having the degree of two different angles? 

Lets try it!

Example:

We have an angle that is 30 degrees, and an angle that is 50 degrees...

50+30= 80 degrees is the sum of those two angles, that is less than 180 so that means it can make another angle to form a triangle. 

Now we have to subtract the sum from 180 degrees to find that third angle! 

READY STEADY GO...

180-80= 100 degrees, so this is the third angle. 

WE HAVE JUST FOUND A TRIANGLE!!
