• 10

• 15

• 17

• 9

Can a triangle be formed with line segments that have lengths 2, 8 and 14 units?

• No, because these line segments wouldn't satisfy the triangle inequality theorem

• No, because there are only two sides to a triangle

• Yes, because these line segments satisfy the triangle inequality theorem

• Yes, because 8< 14
