Answer:

(A)

1= 61° ...(Corresponding angles )

3=1 ...(Vertically opposite angle)

3= 61°

3=6 ...(Corresponding angles)

6=61°

1+2=180° ...(Linear angle)

61°+2=180°

2=180-61

2=119°

2=5 ...(Corresponding angles)

5= 119°

5=7 ...(Vertically opposite angle)

7=119°

4=2 ...(Vertically opposite angle)

4=119°

(B)

2=99° ...(Vertically opposite angle)

2=6 ...(Corresponding angles )

6=99°

6=4 ...(Vertically opposite angle)

4=99°

4+5=180 ...(Linear angle)

99+5=180

5=180-99

5=81°

5=7 ...(Vertically opposite angle)

7=81°

1=5 ...(Corresponding angles )

1=81°

1=3 ...(Vertically opposite angle)

3=81°

This way you can solve (C)

Solution (a) :

Angle 61° = Angle 6 ( They both are vertically opposite angles , which means their angle measure will be equal )

[ Angle 6 = 61° ]

Angle 61° + angle 5 = 180° ( they are a linear pair and the sum of a linear pair is always equal to 180° )

Angle 5 = 180° - 61°

[ Angle 5 = 119° ]

Angle 5 = Angle 7 ( they are vertically opposite angles , which means their angle measure will be equal )

Angle 5 = 119° = angle 7

[ Angle 7 = 119° ]

Angle 4 = angle 5 ( interior opposite angles in a transversal are always equal )

Angle 4 = Angle 5 = 119°

[ Angle 4 = 119° ]

Angle 61° = Angle 3 ( interior opposite angles in a transversal are always equal )

[ Angle 3 = 61° ]

Angle 1 = Angle 3 ( vertically opposite angles in a transversal are equal )

[ Angle 1 = 61° ]

Angle 4 = Angle 2 ( vertically opposite angles in a transversal are equal )

[ Angle 2 = 119° ]

Therefore , angle 1 = 61° , angle 2 = 119° , angle 3 = 61° , angle 4 = 119° , angle 5 = 119° , angle 6 = 61° , angle 7 = 119° .

Solution (b) :

Angle 1 + angle 99° = 180° ( they are a linear pair )

Angle 1 = 180° - 99°

[ Angle 1 = 81° ]

Angle 1 = Angle 3 ( vertically opposite angles in a transversal are equal )

[ Angle 3 = 81° ]

Angle 99° = Angle 2 ( vertically opposite angles in a transversal are equal )

[ Angle 2 = 99° ]

Angle 99° = Angle 4 ( corresponding angles in a transversal are equal )

[ Angle 4 = 99° ]

Angle 1 = Angle 5 ( corresponding angles in a transversal are equal )

[ Angle 5 = 81° ]

Angle 2 = Angle 6 ( corresponding angles in a transversal are equal )

[ Angle 6 = 99° ]

Angle 7 = Angle 3 ( corresponding angles in a transversal are equal )

[ Angle 7 = 81° ]

Therefore , angle 1 = 81° , angle 2 = 99° , angle 3 = 81° , angle 4 = 99° , angle 5 = 81° , angle 6 = 99° and angle 7 =81°.

Solution (c) :

Angle adjacent to angle 1 = 90°

Angle 1 + angle 90° = 180° ( linear pair always sums up to 180° )

Angle 1 = 180 - 90

[ Angle 1 = 90° ]

Angle 1 = Angle 3 ( vertically opposite angles in a transversal are equal )

[ Angle 3 = 90° ]

Angle 90° = Angle 2 ( vertically opposite angles in a transversal are equal )

[ Angle 2 = 90° ]

Angle 3 = Angle 5 ( alternate interior angles in a transversal are equal )

[ Angle 5 = 90° ]

Angle 2 = Angle 4 ( alternate interior angles in a transversal are equal )

[ Angle 4 = 90° ]

Angle 6 = Angle 4 ( vertically opposite angles in a transversal are equal )

[ Angle 6 = 90° ]

Angle 5 = Angle 7 ( vertically opposite angles in a transversal are equal )

[ Angle 7 = 90° ]

Therefore , angle 1 = 90° , angle 2 = 90° , angle 3 = 90° , angle 4 = 90° , angle 5 = 90° , angle 6 = 90° and angle 7 = 90° .
