Are 165° and 1965° coterminal?​
MatroZZZ [7]

two angles are coterminal, namely land on the same spot on the circle.

let's check.

let's firstly divide 1965° by 360°, since 360° is a full circle, that way we know <u>how many full circles are</u> in 1965°.

1965 ÷ 360, gives us a quotient of 5 with some remainder.

5 * 360 = 1800, 5 full circles

if we subtract the full circles from 1965

1965 - 1800 = 165

low and behold, the remainder from that division is 165°  ✔

in other words, 1965°, goes around the circle 5 times and then lands 165° after all that, in the same spot as 165°.
