#### Question 1:

Identify parallel line segments shown in Fig. 15.6 (i) BC ∥ DE
(ii) AB ∥ DC and AD ∥ BC
(iii) AB ∥ DC and AD ∥ BC
(iv) PQ ∥ TS, UT ∥ QR and UP ∥ SR
(v) AB ∥ DC ∥ EF, AD ∥ BC and DE ∥ CF
(vi) BC ​∥ EF, AB ​∥ DF and AC ​∥ DE

#### Question 2:

Name the pairs of all possible paralles edges of the pencil box whose figure is shown in Fig. 15.7 AH ​∥ DG ​∥ CF ∥ BE, ​  AB ​∥ DC ​∥ GF ∥ HE, and  ​AD ​∥ HG ​∥ EF​∥ BC

#### Question 3:

In Fig. 15.8, do the segments AB and CD intersect? Are they parallel? Give reasons. In the given position, segments AB and CD don't intersect, but they can if extended to a point.
No, they are not parallel, as the distance between them is not constant.

#### Question 4:

State which of the following statements are true (T) or which are false (F):

(i) If two lines in the same plane do not interest, then they much be parallel.
(ii) Distance between two parallel lines is not same every where.
(iii) If m ⊥ i, n  i and m ≠ n, then m ∥ n.
(iv) Two non-intersection coplanar rays are parallel.
(v) If ray AB line , then line segment AB ∥ m.
(vi) If line AB line , then line segment AB ∥ m.
(vii) No two parallel segments intersect.
(viii) Every pair of lines is a pair of coplanar lines.
(ix) Two lines perpendicular to the same line are parallel.
(x) A line perpendicular to one of two parallel lines is perpendicular to the other.

(i) T ( It is true for only two co-planar lines)
(ii) F
(iii) T
(iv) F ( Two coplanar rays may neither be parallel nor intersecting)
(v) T ( Line segment is part of a line or a ray)
(vi) T ( Line segment is part of a line or a ray)
(vii) T
(viii) F
(ix) T
(x) T

#### Question 1:

In Fig. 15.17, line n is a transversal to lines l and m. Identify the following

(i) Alternate and corresponding angles in Fig. 15.17 (i).
(ii) Angles alternate of ∠d and ∠g and angles corresponding to angles ∠f and ∠h in Fig. 15.17 (ii).
(iii) Angle alternative to ∠PQR, angle corresponding to ∠RQF and angle alternate to ∠PQE in Fig. 15.17 (iii).
(iv) Pairs of interior and exterior angles on the same side of the transversal in Fig. 15.17 (ii). (i) Alternate Interior angles are: ∠BGH and ∠CHG, ∠ AGH and ∠DHG
​    Alternate Exterior angles are: ∠AGE and ∠DHF, ∠ EGB and ∠CHF
Corresponding angles are: ​∠EGB and ​∠GHD, ​∠EGA and ​∠GHC, ​∠BGH and ​∠DHF, ​∠AGH and ​∠CHF

(ii) The alternate angle to ∠d is ∠​e and alternate angle to ∠g is ∠​b.
The corresponding angles to ∠​f  is ∠​c and ∠h is∠​a.

(iii) In the given figure, 'l' is a transversal line to 'm' and 'n'.
So, the alternate angle of ∠​ PQR is ∠ QRA.
The corresponding angle of ∠​ RQF is ∠BRA.
The alternate angle of ∠​PQE is∠BRA.

(iv) Interior angles on the same side of the transversal line 'n' are: ∠d and ∠ f, ∠a and ∠e.
Exterior angles on the same side of the transversal line 'n' are: ∠c and ∠g, ∠​b and ∠​h.

#### Question 2:

Match column A and column B with the help of the Fig. 15. 18:

 Column A Column B i Vertically opposite angles a ∠PAB and ∠ABS ii Alternate angles b ∠PAB and ∠RBY iii Corresponding angles c ∠PAB and ∠XAQ
