parallel

### 1 Answer | Add Yours

To check if two lines are parallel ,we can apply angle property

1. Draw a transversal line which intersect both lines. So angles will formed with given line and transversal

2. If alternate angles so formed are equal then lines wll parallel.

3. f corresponding angles are equal then also lines will parallel.

4. f cointerior angles are supplementry then ines will parallel.
