Для определения четверти, в которой лежит угол, необходимо соотнести его величину со стандартными интервалами координатной плоскости:

  • I четверть: от 00 raised to the composed with power до 9090 raised to the composed with power II четверть: от 9090 raised to the composed with power до 180180 raised to the composed with power III четверть: от 180180 raised to the composed with power до 270270 raised to the composed with power IV четверть: от 270270 raised to the composed with power до 360360 raised to the composed with power

Решение для заданных углов 1. Угол 100100 raised to the composed with power Угол находится в промежутке между 9090 raised to the composed with power и 180180 raised to the composed with power. Ответ: II четверть. 2. Угол 8080 raised to the composed with power Угол находится в промежутке между 00 raised to the composed with power и 9090 raised to the composed with power. Ответ: I четверть. 3. Угол 300300 raised to the composed with power Угол находится в промежутке между 270270 raised to the composed with power и 360360 raised to the composed with power. Ответ: IV четверть. 4. Угол 700700 raised to the composed with power Для определения четверти необходимо исключить полные обороты ( 360360 raised to the composed with power): 700360=340700 raised to the composed with power minus 360 raised to the composed with power equals 340 raised to the composed with power. Угол 340340 raised to the composed with power находится в промежутке между 270270 raised to the composed with power и 360360 raised to the composed with power. Ответ: IV четверть. 5. Угол -200negative 200 raised to the composed with power Отрицательный угол отсчитывается по часовой стрелке. Чтобы привести его к положительному значению, прибавим 360360 raised to the composed with power: -200+360=160negative 200 raised to the composed with power plus 360 raised to the composed with power equals 160 raised to the composed with power. Угол 160160 raised to the composed with power находится в промежутке между 9090 raised to the composed with power и 180180 raised to the composed with power. Ответ: II четверть. Сводная таблица
