Answer 1

Angle <7 and < 4 are not equal

Explanation:

As we see in the figure angles are formed by a transversal intersecting two parallel lines. If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles. But if we take two angles which are neither supplementary not complementary or any other suitable rule then they are not equal just as angle 4 and angle 7, they do not lie under any rule.

Answer 2

The answer is ∠7 ≅ ∠4 is not true

Explanation:

∵ l // n

∴ ∠2 = ∠6 ⇒ corresponding angles

∵ ∠6 = ∠8 ⇒ vertically opposite angles

∴ ∠8 = ∠2

∵ ∠5 = ∠3 ⇒ alternate angles

∵ ∠4 + ∠5 = 180° ⇒ interior supplementary angles

∵ ∠7 = ∠5 ⇒ vertically opposite angles

∴ ∠4 + ∠7 = 180°

∴ ∠7 ≠ ∠4
