1. Name the pairs of adjacent angles.

2. Find the angle $\angle$JIL from the given figure.

3. Given that AB is a straight line. Calculate the value of x° in the following cases.

4. If the three angles at a point are in the ratio 1 : 4 : 7, find the value of each angle?

5. There are six angles at a point. One of them is 45° and the other five angles are all equal. What is the measure of all the five angles?

6. The angles at a point are x°, 2x°, 3x°, 4x° and 5x°. Find the value of the largest angle?

7. From the figures name the marked pair of angles.

8. Mention two real-life situations where we use parallel lines.

9. Draw two parallel lines and a transversal. Mark two alternate interior angles G and H. If they are supplementary, what is the measure of each angle?

10. In the figure, the lines GH and IJ are parallel. If $\angle$1=108° and $\angle$2 = 123°, find the value of x, y and z.

11. Two parallel lines are cut by a transversal. If one angle of a pair of corresponding angles can be represented by 42˚ less than three times the other. Find the corresponding angles.

12. Can two adjacent angles be supplementary?

13. Can two obtuse angles form a linear pair?

14. Can two right angles form a linear pair?

15. Find x, y and z from the figure.
