1. Inequalities and Triangles
Lesson 5.2
Inequalities and Triangles

2. Exterior Angle Inequality Inequality with Angles
Inequality with Sides
Inequality with Angles
remember:
Exterior Angle =
Remote Int. + Remote Int.
The exterior angle is greater than either of the remote interior angles by themselves
rem. Int. < ext.
Ex:
The biggest side is across from the biggest angle
The smallest side is across from the smallest angle
-The biggest angle is across from the biggest side/ the smallest angle is across from the smallest side

5. List the angles of ΔABC in order from smallest to largest.

6. List the sides of ΔABC in order from shortest to longest.

7. What is the relationship between the lengths of RS and ST?
___

8. What is the relationship between the measures of A and B?
