pls answer fast for this question ​

Answer 1

Answer:

angle 1 and angle 3 is equal and this property is known as vertically opposite angle

and angle 2 and angle 4 are equal due to this property each are 120 degree

so, angle 1,2,3,4 is equal to 360 degree

Step-by-step explanation:

I hope this is clear to you

Answer 2

Step-by-step explanation:

Given,

angle1+angle3 = 120°

we know that vertically opposite angles are equal.

Hence, angle1=angle2 [angle1=angle2=60°]

Now, angle1+angle2=180° [linear pair]

=> 60°+angle2=180°

=>angle2=180°-60°

=120°

And,angle2=angle4. [vertically opposite angles]

so, angle4=120°

We have, angle1=angle3=60° and angle2=angle4=120°
