Ответы

Автор ответа: olecya52

Объяснение:

Луч — это прямая линия, которая имеет начало, но не имеет конца. ... Прямая не имеет ни начала, ни конца, мы можем начертить только часть прямой, так как её можно продолжить в обе стороны; прямую принято обозначать одной или двумя буквами. Отрезок — имеет начало и конец, его нельзя продолжить.
