Unit circle Crossword

A squared plus B squared equal C squared
A = 1/2bc•sinA
SinA/a = SinB/b = SinC/c
C squared = A squared + B squared - 2ab cosC
Each of four quarters of a circle.
__________ angles can be found in Quadrants I & II
_________ angles can be found in Quadrants III & IV
Which way does it go from quadrant 1 to quadrant 4 (clockwise or counterclockwise)
The ray where the measurement of an angle starts.
Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.
The common endpoint of two or more rays or line segments.
A central angle is an angle whose vertex is the center of a circle and whose legs (sides) are radii intersecting the circle in two distinct points.
an angle lying in the Cartesian plane whose vertex is at the origin and whose initial ray lies along the positive x-axis.
The ray where the measurement of an angle stops.
That part of a circle that lies between two lines that intersect it.
