Ответ:

Щоб довести, що a║b (кути a та b паралельні), давайте розглянемо, які можливі значення цих кутів і як вони пов'язані з паралельністю ліній.

Відомо, що сума внутрішніх кутів на одному боці лінії при паралельних лініях дорівнює 180°. Таким чином, якщо ⦟3 + ⦟8 = 180°, то ці кути знаходяться на одному боці лінії та можуть бути внутрішніми кутами відносно паралельних ліній.

Отже, доведено, що a║b.
