WebJul 7, 2024 · Because a right triangle can only measure angles of 90 degrees or less, the circle allows for a much-broader range. Positive angles The positive angles on the unit circle are measured with the initial side on the positive x-axis and the terminal side moving counterclockwise around the origin.The figure shows some positive angles labeled in both … WebApr 22, 2024 · Explanation: We know that. Q1 is from 0 to π 2 = 1.5708 radians. Q2 is from π 2 = 1.5708 to π = 3.1416 radians. Q3 is from π = 3.1416 to 3π 2 = 4.7124 radians and. Q4 is from 3π 2 = 4.7124 to 2π = 6.2832 radians. Now −2 radians is equivalent to −2 + 2π = − 2 + 6.2832 = 4.2832 radians. Hence −2 radians lies in Q3.
WebMar 26, 2016 · Because the bold arc is one-twelfth of that, its length is ð/6, which is the radian measure of the 30-degree angle. The unit circle’s circumference of 2ð makes it easy to remember that 360 degrees equals 2ð radians. Half the circumference has a length of ð, so 180 degrees equals ð radians. If you focus on the fact that 180 degrees equals ...
