Answer:

Step-by-step explanation:

to prove: angle 1 + angle 2 + angle 3 = 180

proof:

angle 4 = angle 2( alternate interior angle); eq 1

angle 5 = angle 3(alt int); eq 2

add both equations

angle 4 +angel 5= angle 2 + angle 3

add angle 1 on both sides

angle 1 + angle 4 + angle 5 = angle 1 +angle 2 +angle 3

angle 1+ angle 2+ angle 3 = 180

hence proved
