Trigonometry Index Unit Circle. Jun 9, 2023 · In a unit circle, any line that starts at the center of the circle and ends at its perimeter will have a length of 1. So, the longest side of this triangle will have a length of 1. The longest side of a right triangle is also known as the "hypotenuse." The point where the hypotenuse touches the perimeter of the circle is at √3/2, 1/2.
