Be one of the first to ride the Atlanta Streetcar. The route runs in an East-West loop from the Historic Auburn Avenue to Centennial Olympic Park traveling on multiple streets with mixed traffic. The fare will be free for through the end of 2015.
 SSS  is when we know three sides of the triangle, and want to find the missing angles. To solve an SSS triangle: 1  use The Law of Cosines first to calculate one of the angles. 2  then use The Law of Cosines again to find another angle. 3  and finally use angles of a triangle add to 180Â° to find the last angle.
Figure %: An angle whose vertex lies outside of a circle. In part (A) of the figure above, the measure of angle 1 is equal to one-half the difference between the measures of arcs JK and LM. In part (B), the measure of angle 2 is equal to one-half the difference between the measures of arcs QR and SR.n angle whose vertex lies in the interior of a circle, but not at its center, has rays, or sides, that can be extended to form two secant lines. These secant lines intersect each other at the vertex of the angle. The measure of such an angle is half the sum of the measures of the arcs it intercepts.
