The measure of the third side of a triangle must be greater than the difference of the other two sides, and less than the sum of the other two sides.
Using this rule, the third side must be greater than 9 - 4 = 5 cm and less than 4 + 9 = 13 cm.
Therefore, the measure that cannot be the measure of the third side is 15 cm.
Two sides of a triangle measure 4 cm and 9 cm. Determine which of the following choices cannot be the measure of the third side.(1 point)
