A triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, the two sides given are 4 cm and 9 cm.
4 cm + 9 cm = 13 cm
Therefore, any choice greater than or equal to 13 cm cannot be the measure of the third side.
So, the third side cannot be 10 cm or 10 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)
