Triangles Review

Two sides of a triangle have side lengths of 17 meters and 12 meters.  What is the range of possible lengths for the third side?

• 12 < x < 17
• 12 < x < 29
• 5 < x < 17
• 5 < x < 29

Tell whether the angles are adjacent or vertical. Then find the value of x

• Adjacent; x= 30

• Adjacent; x= -30

• Vertical; x= 30

• Vertical; x= 10

Tell whether the angles are adjacent or vertical, then find the value of x.

• Adjacent; x = 43

• Adjacent; x = 123

• Vertical; x = 43

• Vertical; x = 123

Click all the pair(s) of adjacent angles.

• < DEI and <HEI

• < FED and < GEH

• < FED and < GEF

• < HEG and < HEI

• < FEG and < DEH

Find the missing third angle.

• 55

• 5

• 65

• 85

Tell whether the angles are complementary, supplementary, or neither.

• complementary

• supplementary

• neither

• I can't remember....(go look at notes!!!)
