Anbu has marked the angles as shown below in (i) and (ii). Check whet

1.	Anbu has marked the angles as shown below in (i) and (ii). Check whether both of them are correct. Give reasons
Answer» (i) m and n are parallel lines. l is the transversal. Interior angles on the same side of the transversal are supplementary. But here it is 75 + 75 ≠ 180° 105 + 105 ≠ 180° ∴ Angles marked are not correct (ii) m and n are parallel lines. l is the transversal. Corresponding angles must be equal. So here the marking is wrong.

Answer»

(i) m and n are parallel lines. l is the transversal.

Interior angles on the same side of the transversal are supplementary. But here it is

75 + 75 ≠ 180°

105 + 105 ≠ 180°

∴ Angles marked are not correct

(ii) m and n are parallel lines. l is the transversal. Corresponding angles must be equal. So here the marking is wrong.
