Question

In the figure, L|| m, m || n and p || q.
Find the angles 1, 2, 3, 4, 5, 6.
please answer with explanation.


your help will be appreciated​

Answer 1

★ Measurement of angle 7 = 120° (measurement of supplementary angles are same)

★ Measurement of angle 6 = 180° - 120° = 20°

★ Measurement of angle 8 = 20° (measurement of opposite angles is same)(angle 6 and 8 are opp)

★ Measurement of angle 5 = 120° (bcoz it is opposite angle of 7)

★ Measurement of angle 9 = m of supplementary angles is 180° = m of angle 5 + m of angle 9 = 180 = m angle 9 = 60°

★ Measurement of angle 4 = 120°

★ Measurement of angle 1 = 120° (opposite angle of 4)

★ Measurement of angle 2 = 180° - m of angle 120°

= 60°

★ Measurement of angle 3 = 60° (it is opp to angle 2)
