Farid believes that both lines are parallels but Azam thinks otherwise. In your opinion, what must
they do to prove the true answer?
Dua garisan selari mempunyai jarak yang sama pada mana-mana titik yang
berseranjang antara dua garisan. Gunakan pembaris untuk mengukur garis
AC dan BD. Jika jarak kedua-duanya adalah sama bermaksud kedua-dua
garisan tersebut selari. Ia kelihatan tidak selari disebabkan oleh ilusi optik.
Two parallel lines have the same distance at any point that perpendicular between two lines. Use
ruler to measure AC and BD line. If the distance is the same, the two lines are parallel. It looks
non-parallel due to the illusion of optic.
