1 4.7 Triangle Inequalities

2 Relationship between SIDES and ANGLES:
In every triangle, the longest side is opposite the largest angle. In every triangle, the shortest side is opposite the smallest angle.

3 Example 1: Name the angles from largest to smallest:

4 Example 2: Name the sides from longest to shortest:

6 A Few More…

7 Can ANY 3 segment lengths make a triangle?

8 Triangle Inequality Theorem
The SUM of the lengths of ANY 2 SIDES of a triangle is GREATER THAN the length of the third side.
