5.5 Inequalities in Triangles
Learning Target I can use inequalities involving angles and sides in triangles.
In Triangles, the longer side lies opposite the larger angle.
Lets apply this and do on the worksheet
Lets do 1-6
Triangle Inequality Theorem: The sum of the lengths of any two sides of a triangle is greater than the length of the third side
Can a triangle have sides with the given lengths? – 3 ft, 7 ft, 8 ft – 3 cm, 6 cm, 10 cm
Try 7-15 on your worksheet.
Lets look at together
RECAP – Can you list angles and sides in order from smallest to largest. – Can you determine if a triangle can have the given lengths.
