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

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.
Page No 15.3:
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)
(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)

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.
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.
