Three line segments whose lengths are equal to three given numbers form the sides of a triangle if the sum of the lengths of every pair of two of these is greater than the length of the third.

The length of one side of a right triangle is 4.5 cm and the length of its hypotenuse is 7.5cm Find the length of its third side.

The difference between the lengths of any two sides of a triangle is smaller than the length of third side.

Two sides of a triangle are of length 4 cm and 10 cm. If the length of the third side is a cm, then

Draw five triangles and measure their sides. Check in each case, if the sum of the lengths of any two sides is always less than the third side.
