    Trigonometry (1st Grading Period) Angles and Measures • Angle – is formed by two rays with a common endpoint. • Standard Position: An angle inscribed in a circle whose center is at the origin is said to be in “standard position” if one of the sides of the angle coincides with the positive ray of the x-axis. • Stationary Ray – “Initial Side” of the angle (the x-axis, abscissa side; the one that is NOT MOVING; the starting point of every angle) • Rotating Ray – “Terminal Side” of the angle

    Difference Between Euclidean and Spherical Trigonometry

    Difference Between Euclidean and Spherical Trigonometry 1 Non-Euclidean geometry is geometry that is not based on the postulates of Euclidean geometry. The five postulates of Euclidean geometry are: 1. Two points determine one line segment. 2. A line segment can be extended infinitely. 3. A center and radius determine a circle. 4. All right angles are congruent. 5. Given a line and a point not on the line, there exists exactly one line containing the given point parallel to the given
