Respuesta :
That would be vertical angles if they are angle opposite each other when 2 lines intersect.
Answer:
vertical angles
Step-by-step explanation:
Refer the attached figure .
Since we are given that Two lines intersecting creating four angles with the left angle labeled one and the angle to the right labeled two.
So the required figure is attached .
Thus ∠1 and ∠2 are vertical angles.
Definition of vertical opposite angles :Each of the pairs of opposite angles made by two intersecting lines.
Hence by definition ∠1 and ∠2 are vertical angles.
