#### SUMMARY • Corresponding angles: ∠1 &∠5, ∠4 &∠8, ∠2 &∠6, ∠3 &∠7 are pairs of corresponding angles.
• Alternate interior angles: ∠3 &∠5, ∠2 &∠8 are the pairs of alternate interior angles.
• Consecutive interior angles: ∠2 &∠5, ∠3 &∠8, are pairs of consecutive interior angles.
• Vertically opposite angles: in figure, ∠1 = ∠3, ∠2 = ∠4, ∠5 = ∠7 &∠6 = ∠8.

#### SECTION – I(OBJECTIVE) • In the given fig if l II m, n II p and ∠1 = 85° then ∠2 is

4. 30°
• If the supplement of an angle is three times its complement, then angle is:
1. 40°
2. 35°
3. 50°
4. 45°
• Two angles whose measures are a & b are such that 2a – 3b = 60°, if they form a linear pair then find4a/5b.
1. 0
