These unit circle notes delve into the mathematics of the unit circle Focus is placed on an understanding of side lengths of 45 – 45 – 90 triangles and 30 – 60 – 90 triangles This understanding is then transferred to the unit circle Students willSpring Trig Note Sheets and ConnecttheDots 1, 2 pdf of circles, angles, degrees, radians, triangles, square 3, 4 pdf of and triangles and trig functions of 30°, 60°, and 45° angles 5 gif of answers to 3 and 4 all functions of the 30s, 45s, and 60sRight triangles with a set angle scheme that helps with the determining of its lengths triangle has sides {adjacent with 30=x, opposite of 30=x¬3, hypotenuse=2x} triangle has sides {across or adjacent to 45=x¬2\2, hypotenuse=x}
