How Do We USe the Triangle Inequality Thereom?

 

 

Triangle Inequality Theroem

 

The sum of any two sides of a triangle must greater thn the meausre of the third.

 

 

Examples:

In the example above, it shows that any two sides must be greater than the third side to create a triangle.

This is another example to show how triangle inequality theroem works. If you add 4+7, it would equal 11, which is greater than 8. If you add 7+8, it would equal 15, which is bigger than 4. Also if you add 4+8, it would equal 12, which is still greater than 7.

 

In order for the theorem to work, any two sides must be greater than the third side, other wise it won't be considered a triangle.
