In the given figure, is 'l parallelto 'm' ? Justify |
|
Answer» Suppose l ║ m, Then n is transversal.∵ If TWO parallel lines intersected by transversal then,Consecutive INTERIOR angles are Supplementary.∴ 126° + 44° ≠ 180°⇒ 170° ≠ 180°Here, Consecutive Interior angles are not Supplementary.Hence, l ∦ m, l is not parallel to m.Some Important Terms:-If two parallel lines intersected by a transversal then:-Their Alternate interior angles are EQUAL.Their Corresponding angles are equal.Sum of Consecutive interior angles are 180°.Their Alternate exterior angels are equal.Vertically Opposite angles are equal. |
