01. ABCD is a parallelogram in which ∠A = 110°. Find the measure of each of the angles ∠B, ∠C and ∠D.
2. Two adjacent angles of a parallelogram are equal. What is the measure of each of these angles?
3. Two adjacent angles of a parallelogram are in the ratio 4 : 5. Find the measure of each of its angles.
4. Two adjacent angles of a parallelogram are (3x - 4)° and (3x + 16)°. Find the value of x and hence find the measure of each of its angles.
5. The sum of two opposite angles of a parallelogram is 130°. Find the measure of each of its angles.
6. Two sides of a parallelogram are in the ratio 5 : 3. If its perimeter is 64 cm, find the lengths of its sides.
7. The perimeter of a parallelogram is 140 cm. If one of the sides is longer than the other by 10 cm, find the length of each of its sides.
