Question

in the adjacent figure the lines l and M are parallel and n is a transversal fill in the blanks for all the situations given below​

Answer 1

Answer:

Use the linear pair property in (i).

Use the co-interior angle property in (ii)

Use the corresponding angle property in (iii).

Use the alternate interior angles property in (iv)

Now, try it urself coz it will develop the confidence inside u and I can answer them but it will help u in exam!!

Answer 2

Answer:

i) 180° - ∠1 (Sum of angles on a straight line is 180°)

 180° - 100° = 80°

(ii) ∠3 + ∠5 = 180° (Sum of co-interior angles is 180°)

   80° + ∠5 = 180°

   ∠5 = 180° - 80° = 100°

(iii) ∠2 = ∠6 = 80° (Corresponding angles are equal)

(iv) ∠4 = ∠5 = 100° (Alternate interior angles are equal)
