Find one positive angle whose is
WebIt is possible for more than one angle to have the same terminal side. Look at Figure 16. The angle of 140° is a positive angle, measured counterclockwise. The angle of –220° is a negative angle, measured clockwise. But both angles have the same terminal side. WebReference angle. Definition: The smallest angle that the terminal side of a given angle makes with the x-axis. Try this: Adjust the angle below by dragging the orange point around the origin, and note the blue reference angle. In the figure above, as you drag the orange point around the origin, you can see the blue reference angle being drawn.

For instance, if our given angle is –110°, then we would add it to 360° to find our positive angle of 250° (–110° + 360° = 250°). Now we would have to see that we’re in the third quadrant and apply that rule to find our reference angle (250° – 180° = 70°). See more Imagine a coordinate plane. Let’s say we want to draw an angle that’s 144° on our plane. We start on the right side of the x-axis, where three o’clock is on a clock. We rotate … See more The reference angle always has the same trig function values as the original angle. Notice the word valuesthere. The sign may not be the same, but the value always will be. This is useful for common angles like 45° and 60° that we … See more When an angle is greater than 360°, that means it has rotated all the way around the coordinate plane and kept on going. In order to find its … See more How we find the reference angle depends on the quadrantof the terminal side. When the terminal side is in the first quadrant(angles from 0° to 90°), our reference angle is the same as our given angle. This makes … See more
