Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options.

For three lengths to form a triangle, the third side must be greater than the difference of the other two sides and less than their sum. Here, 28 − 12 = 16 and 28 + 12 = 40, so the third side must be more than 16 cm and less than 40 cm. Both 24 cm and 38 cm fit this range.
