The line segment is 20 units long. If the line segment is translated up 6 units and left 8 units, which statement is true?

• The length of the resulting line segment is 4 units because translation decreases length

• The length of the resulting line segment is 20 units because translation preserves length

• The length of the resulting line segment is 34 units because translation increases length

• The length of the resulting line segment cannot be determined
