The unit circle along with trigonometric functions is a common topic for high school geometry and beyond. This app can help students to understand coterminal angles and trig functions. You are not limited to 360 degrees like most other apps.
Infinite Unit Circle is a free educational mobile app By Chad Cabrera.It helps students in grades HS practice the following standards HSG.C.A.1,HSG.C.A.2,HSG.C.A.3.
1. HSG.C.A.1 : Prove that all circles are similar.
2. HSG.C.A.2 : Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.
3. HSG.C.A.3 : Construct the inscribed and circumscribed circles of a triangle, and prove properties of angles for a quadrilateral inscribed in a circle..
