1.	In Fig, name each linear pair and each pair of vertically opposite angles:
Answer» Two adjacent angles are said to be linear pair of angles, if their non-common arms are two opposite rays. Therefore linear pairs are listed below: ∠1 and ∠2 ∠2 and ∠3 ∠3 and ∠4 ∠1 and ∠4 ∠5 and ∠6 ∠6 and ∠7 ∠7 and ∠8 ∠8 and ∠5 ∠9 and ∠10 ∠10 and ∠11 ∠11 and ∠12 ∠12 and ∠9 The two angles are said to be vertically opposite angles if the two intersecting lines have no common arms. Therefore supplement of the angle are listed below: ∠1 and ∠3 ∠4 and ∠2 ∠5 and ∠7 ∠6 and ∠8 ∠9 and ∠11 ∠10 and ∠12

Answer»

Two adjacent angles are said to be linear pair of angles, if their non-common arms are two opposite rays.

Therefore linear pairs are listed below:

∠1 and ∠2

∠2 and ∠3

∠3 and ∠4

∠1 and ∠4

∠5 and ∠6

∠6 and ∠7

∠7 and ∠8

∠8 and ∠5

∠9 and ∠10

∠10 and ∠11

∠11 and ∠12

∠12 and ∠9

The two angles are said to be vertically opposite angles if the two intersecting lines have no common arms.

Therefore supplement of the angle are listed below:

∠1 and ∠3

∠4 and ∠2

∠5 and ∠7

∠6 and ∠8

∠9 and ∠11

∠10 and ∠12
