The third side of a triangle must be greater than the absolute value of the difference of the other two sides and less than the sum of the other two sides.
In this case, the two sides given are 4 cm and 9 cm. The third side must be greater than |4-9| = 5 cm and less than 4+9=13 cm.
Therefore, the third side cannot be 10 cm, as it falls outside of the valid range of 5-13 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)
