What are corressponding angles

Step-by-step explanation:

The angles in which one angle is lies inside and another angle is lies outside of of same side of transversal is called corresponding angles. The corresponding angle are equal if there is parallel

line .

1.   J=20, f= 28, H=42

2. 240 + 241 + 242 = 723

Step-by-step explanation:

J= 30- 12= 18+2= 20

F= 30-2=28

H=30+12=42

2.

240 + 241 + 242 = 723
