Do the side measures form a triangle?

Figure out if the given lengths form the sides of the triangle by applying the triangle inequality theorem. Add any two lengths, if their sum is greater than the third side, then the sides form a triangle.

Range of the Third Side

Compute the range of possible measures of the third side of the triangle in this set of worksheets. The difference between the two sides makes the lower range, while the sum of the two sides forms the upper range.

Least possible measure of the Third Side

Subtract the two given side measures and add 1 to the difference to determine the least possible whole number measure of the third side. Reaffirm the triangle inequality theorem with this worksheet pack.

Greatest possible measure of the Third Side

The length of a side of a triangle is less than the sum of the lengths of the other two sides. Add up the two given sides and subtract 1 from the sum to find the greatest possible measure of the third side.

Multiple response

Reiterate the triangle inequality theorem with multiple response questions. Determine the least and greatest possible measures of the third side and also check if the given measures form a triangle or not.
