2. 5.5 Inequalities in Triangles

3. Learning Target I can use inequalities involving angles and sides in triangles.

4. In Triangles, the longer side lies opposite the larger angle.

5. Lets apply this and do 16-21 on the worksheet

6. Lets do 1-6

7. Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle is greater than the length of the third side

8. Can a triangle have sides with the given lengths? – 3 ft, 7 ft, 8 ft – 3 cm, 6 cm, 10 cm

9. Try 7-15 on your worksheet.

10. Lets look at 22-27 together

11. RECAP – Can you list angles and sides in order from smallest to largest. – Can you determine if a triangle can have the given lengths.
