| 1) Let us find out how long the side BC of the triangle ABC has, if it is known that it is 4 cm less than the length of the side AB, and the length of the side AB is 10 cm.

10 – 4 = 6 cm.

2) Find out what is the sum of the lengths of the two sides, if it is known that the AB side is 10 cm, and the BC side length is 6 cm.

10 + 6 = 16 cm.

3) Let us find out what is the length of the third side of the ABC triangle, if it is known that its perimeter is 24 cm, and the sum of the lengths of the first two sides is 16 cm.

24 – 16 = 8 cm.

Answer: BC length = 6 cm and AC = 8 cm.
