Find the sides and angles of the parallelogram ABCD if its perimeter is 32 cm, AB = 6 cm.

Let’s solve this task in steps and explain each of them in detail.
1) 6 + 6 = 12 centimeters – the sum of the lengths of the side AB and CD, since the opposite sides in the parallelogram are equal;
2) 32 – 12 = 10 centimeters – the sum of the side lengths BC and AD;
3) 10: 2 = 5 centimeters – the lengths of the sides BC and AD, since their sum is 10 centimeters and they are equal to each other.
Answer: 6 centimeters; 6 centimeters; 6 centimeters.
